Can you extract a certain part of lyra to build from

Hi there,
Not a professional dev or anything, just wanting to build some little levels for myself and the kids to muck around with.
We are trying to build a shooter that we can base our levels from and the ‘shooter gym’ level in Lyra is perfect. Is there a way to export that level, the player, ai, health etc parts to a new project and leave all the other maps and assets behind. We are just going to grab some stuff from Quixel or the marketplace to build our levels with but that part of Lyra is perfect for the ‘pew pew’ as the kids say, part of what we need.

Any suggestions here would be amazing.

Thanks.

S.
