Jason,
Thank you for your response. I downloaded and installed Ribbon Workbench as you suggested and I've been going through the How-To's to begin learning the process. I'm stuck, however, on one thing. The button I'm trying to hide/edit does not show in the ribbon items when editing the ribbon for my custom entity.
When I open the "Team Members" list form to add/edit/delete members from the team, there are two ADD buttons. One is Add New and one is Add From Existing. The Add From Existing button does not show up in Ribbon Workbench and I can't seem to figure out where to find it to change its behavior. Am I missing something simple or am I barking up the wrong tree?
Any help would be greatly appreciated.
Sincerely,
Glen
