I have a lighting circuit with several slim LED pot-lights that are controlled with a dimmer switch. I added a second switch (see diagram below) so that I can independently turn one of the lights off while the others in the room remain on.

select lights in a circuit turned off by second switch

Hopefully my diagram makes sense, I'd like to change things so that two lights are now turned off by that same switch.

EDIT:

Thanks for you answers! How does the following updated diagram look?

I'm trying to retain the existing wiring as much as possible in case I ever need to remove the second switch and revert my changes, hence the seemingly unnecessary junction boxes :)

Using your own picture seems that you can connect up Light B the same way that Light A is connected.

More like this. Forgive the crude drawing. Two chains of lights, one switched, the other double-switched. You don't need an extra junction box. Take a feed off any of the lights, the one closest to the second switch position. Run live and neutral to the switch. From there go to any of the double-switched lights, and from there chain them just like the first chain.

It's important that all the double-switched lights' neutral wires return via the same path as their live wires. You cannot leave the neutrals connected to the old chain and only modify the lives.
