Or would that be something we could add to a cell with an item type?

A small bane of my existence is the need to place cells when I can't remember which library they came from. Our libraries are documented, but that's still thousands of cells. Most of the libraries come from our client, and if I'm honest, they are not the most organized, nor has much time been spent at the source to keep them clean and relevant. Duplicate symbols can be found in more than one library, the division between cell libraries is a bit arbitrary, and sometimes there is more than one symbol for the same thing (left over from a previous iteration).

Today I am looking for the cell that is used on cross sections to label proposed R/W. I can see that the corresponding cell for existing R/W is in the drawing, and it would be REALLY nice to be able to look at the information for that cell and see which library it is in so that I can go straight to the library for the other cell I need. I know it's out there, I've used it before, and I seem to recall that it's not in a "logical" cell library.

Is that something that could be managed with an item type?
