Best/Easy way to save all project sounds into pool?

Is there a good way to get all the sounds I have in a project into the pool rather than one at a time?

The Sound Manager should be helpful. AFAIK the [YES/SAVE] button can be used to select/deselect single sounds.

But not in a project.

So I’m in a project.
It’s got like 50 sounds scattered across like 10 patterns/kits
Pool is empty because I’ve not “saved” or moved any into it yet
I want to have it so that the pool has all my sounds that are already in my project so when I create more kits (in this project), I can just choose from the pool.
I know I can copy paste, but I figured there may be a way to say “put all sounds in this project into the pool”

Everyone in the pool.
