Feature Tree

This is perhaps a strange question, but I shall ask itnonetheless.

It is possible to add something to the "feature" tree which is nota feature?
We, like most companies I suspect, have a good deal of mirroredparts. With the mirrored part you can see from the feature tree theoriginal handed part as it were; you cannot from the original partsee that a mirror has already been created.

It would be nice to be able to add something obvious, where theuser can readily see it (ie the feature tree) something whichindicates that a mirror of that part exists.

Slightly out of the box idea but would welcome ideas suggestionshow other people deal with this.

Thanks
