Find the center of an XRef?

Hi, I'd like to put a MText label over the center of each of a few
dozen Xrefs in my drawing --programmatically.
Something akin to the extmin & extmax of the Xref divided by 2
(accounting for rotation) would do it. So I guess I'm asking is
there a way for me to peak at the extmin & extmax of an Xref without
opening the Xref drawing?
I still like AutoLISP but I can do VBA if prodded. I got AC2K.

If they're all the same you could make a block with the insertion positioned
relative to the XREF insertion to do the job.

 

Thanks for the thought but all counted I have hundreds of Xrefs and
changing their insertions would necessitate editing hundreds of
drawings. Also a center origin for the drawings is not as useful in
most cases (except this one).

 

I said, "If they're all the same.....", then you wouldn't be changing
anything. Don't know what you mean about "center origin".
