CentrED building Multis

[sid]

Greetings, first of all let me bow to you, because without your great tools, me and my UO team would be lost.

Now, let' s move to my request. Could it be possible to build houses (or anything) contained in multis?
Multis are basically arrays of statics with relative-defined coordinates, so I don't think it should be problem. But for me, it is. I am only a little advanced "programmer" using C# and PHP, but Pascal is one big mystery. Thanks a lot in advance, at least for your reply.
