No way to do this, other than brute-forcing it (i.e. generating maps untils their doors coincide with marked locations), sorry. I don't know how useful this is for you, but the entrance (the staircase) always has the same coordinates (0, 0).
Thanks for the reply, like I said not a major issue just a little time saver. Great work on this generator, most others I used just don't have the same quality
