Visibility of component documents in browser assembly tree

In web browser assembly tree, it would be good to have a column indicating presence of documents, or document count or similar. 

Context: be able to scan down a large assembly tree and identify which line items have a drawing in the documents tab without having to go into each one individually.

Could be just an attachments icon, symbols by type (e.g. PDF, DXF), or a document count. E.g. if all you typically upload to an assembly are drawings, then you'll know which parts have drawings and which don't by scanning down the column and seeing document counts in that column.
