In Search of a Side Door Managing Links

I wrote about the Manage Links dialog yesterday. Something else has been bugging me about it so here's another post. I'd love a side door to Import a file from the Manage Links dialog!!! It would be nice to be able to click Import File when I've realized that I need to do that instead of closing the dialog and then clicking the front door buttons for the task. Each tab could have its own side door for the appropriate file type. Crazy?

There are other precedents like the Materials browse button in the Edit Assembly dialog for walls, floors, roofs, ceilings. Another precedent, the browse button for accessing Assembly Code data?

See, not so crazy me thinks!!
