Somewhat of a challenge...

I'm going from a single light to recessed lighting in my studio condo.
There is a single pole switch that this single light is currently connected to.

I'm going to install about 10 recessed lights, but; I want only 5 lights to turn on when I press XYZ button and all lights to turn on when I press ABC button.

My main challenge here is with this switch, it's housed in a concrete wall with hard drawn solid copper 10AWG wires, so there's no options for rewiring anything, all wiring goes into in a concrete wall and ceiling.

Is there anything I can use to control an array of 10 different lights with an immovable/modifiable single pole switch?

My idea was to leave the single pole switch as is with the dimmer, and have some kind of wireless routing panel in the closet that would allow me to then switch between the lighting "zones" (if that's what they're called) using a wireless switch installed "next to" the current switch. I see Lutron makes some interesting products, but I'm not sure which will do what I need, or the less expensive alternatives. Expense isn't a serious issue here, but I'm not trying to spend $4000-$6000 on a solution.

Does anyone have any idea what I should be searching for, or the proper name of what I'm looking for to make this work?

Thank you in advance for your help

This can be done with wireless smart bulbs (or fixtures) and a remote switch in place of your current light switch. I'm going to describe how to do it with the Phillips Hue series, since I'm more familiar with them, but other brands will probably work just as well.

For the lights themselves, if you have not already bought the fixtures, you can get Hue recessed fixtures with built-in communication and dimming capability, and you'll never have to change a bulb.

If you already have fixtures, you can simply add smart bulbs to them, but make sure they fit and will cool adequately!

Then, to control it at the location of your current light switch, install a wall-mounted remote.

For your current light switch, you can either leave it in place as a way to disable the whole system, or remove and bypass it to supply the Hue fixtures with always-on power and let them turn themselves on and off remotely (recommended if you want to use any other smart features, like timer on/off, or google home/alexa connectivity). If you remove the current switch, you can install the remote over the top of a cover plate. Otherwise, you can install the remote on the wall next to the current switch.

Lastly, you will need a Hue hub to tie it all together. You can place this wherever you want -- it need not be on the same circuit as the lights. This will also give you voice control of the lights.

You can learn more about the Hue line here. Again, I don't mean this as a specific endorsement -- Hue are popular and capable, but not the cheapest, and there are competitors that are also well regarded.
