Is it possible to make doors open when enemies die in Boom format

[Shakariki Heisenberg]

I've searched everywhere and the only way I can do it is through Hexen , UDMF or some other comp.
so is it possible to do that? like through Dehacked or map info or something else.
btw Im using Doom builder X With Slade3 and Comp lev9 (Boom)as i said in the title thank you in advance.

UMAPINFO bossactions, if you want your map to be playable on a reasonable amount of ports that support boom. It's still limited to "kill all enemies of type X", so you'll have to make dehextra copy of required enemy if your idea is something along the lines of "kill these 20 imps in a specific room, while other imps exist on the map". For several types of enemies in a room, combine with voodoo closet a-la "flip all 3 switches to open the door" setups.
