Weld Command and UV map

[gap]

Hi there,

this is a problem I run across quite often: let's say that I am modelling an object composed of many identical modules adjacent to each other. What I would do, is creating just one of those modules, unwrap it and then duplicate/displace it as needed.
The problem arises when I combine and weld the duplicated objects: it seems that, besides welding the coincident faces, Wings also tries welding the UV projections of faces adjacent to the welded faces, screwing them up. Is there a way to avoid that, other than UV mapping each module separately after the welding process (with waste of time) or not using the weld command at all (with an avoidable increase of poly/vertex count in the final model)?
