Flags are used for a "real" monsters, not for their alternates (different graphics). In that case flags for the original monster are set the same as for its alternates.
But sometimes monster #1, #2 and #3 (various bitmaps of the same monster, wchich means its alternations) are much smaller/taller than monster #0 (original bitmap). is it possible to arrange those flags to each monster independently so that the door animation stops correctly to its size? I want to avoid the situation that door stops inadequanly to monster`s size.
For example over a small rat door should close at 1/4 of its size, while over a huge rat door should close at 1/2 of its size, or even 3/4, depending of its size.

Is there any way to do that?

No reasonable way to do that. Everything
about the monster and its alternates are
identical. Including its size.

It is the designer's responsibility to assure
that the alternate graphics are 'proper' for
the underlying monster.
