Property Tab Builder

Hello chaps,

I created a custom property tab a few years ago which contained a drop down menu with 10+ options. I'm now trying to create a new custom property file but seem to be limited to only 4 options. Do you know how I can get around this?

Also, where is the best place to add a part description? I want this description to be used in drawings and to be used as a search criteria when looking for a part. I've always done this using a tab in the property builder (and linking it to the drawing) but I don't believe this works as a search criteria when searching for a part. I've noticed you can add a description when saving the part which I imagine links to explorer? Can you link this to the drawing?

(using Solidworks Explorer to control parts)
