Can we change private to public?

In later waves, I would like to add more player to help me to beat it.

But at the beginning I would like to solo, that is more easy than multi player.

Most of us want that function, but we don't have it yet.

Yeah this is on the wishlist of many. Some would like to build then open the game, or as yourself if it gets too tough to keep everything repaired and no mates are about to just open it to pubs.

Or vice versa you have 1 or 2 good pubs so you switch it to private.

Yep would be nice in both direction.
