Disable Enemies?

With any of the new features (Room States, scripting, ect), is it possible at all to disable enemies from spawning? What I'd like to do is have a little area with some enemies, then you defeat their leader in a little mini-dungeon, and they all go away

The only way I think I could do this is to remake the screens on another map, and have a room state change a tile warp to warp Link to those screens instead of the regular ones, but that would be a bit of work

Is it possible, or am I just dreaming?

I think the "Permanent Enemies->Secret" screen flag, with no secret to activate, keeps them from respawning, but you can't activate it from another screen, if thats what you want. Maybe theres some creative way to do it that doesn't use so much memory.

Well, I know it's possible with scripts... But to do it within the editor without copying the map... hmm...

It sounds like this is already completely doable with Boss Flags, unless I just completely misunderstand you.
