Attached is a document that will show how to add a Tab/Edge Pull to Component Library 50.7. Values are in Metric. I also included the Tab/Edge Pull drawing files that I used.

DISCLAIMER: This is my own take on the procedure and have tested on various configuration. Please test to make sure it will work on your setup. This procedure includes modifying the Door Single Slab, Door Left Slab and Door Right Slab sub-assemblies only.
