Faces from different objects in the same UV window. Possible?

[kugelfang]

Hello,

Is it possible to have various faces from different objects show up in the same AutoUV window without having to combine the objects?

Or, is it possible to apply the Scale|Normalize Sizes command to multiple UV windows so that the faces in the multiple windows are sized relative to each other?

Either work flow would work for me. As it is now, to normalize UV face sizes between different objects requires combining the objects. Then, separating them and losing all the previous object properties (name, etc.). If the objects are themselves collections of smaller combined objects, reconstituting them can be tedious. I'd like to maintain the object information but have the UV coordinates normalized.

Thanks
