How would I modify this system to be able to use multiple parts for the walls

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I would like to change this system (Cutout Wall with a Part - #4 by Hanfian) so that instead of it being only able to use 1 wall part for the wall, it can use multiple.

  2. What is the issue? Include screenshots / videos if possible!
    It currently only takes in 1 part and 1 part only for the wall to cut and because I am making a gun game with breakable walls, I need it to be able to shoot possibly in areas over what might have been already cut.

  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    To be completely honest, I haven’t really tried anything because I don’t have a understanding of the system but I was hoping somebody could either help me figure out the system or even point me towards a existing system so that I can do this.

Thanks if anybody can help!
