I'm trying to set up a function in the custom properties tab that will utilize the checkbox control. The goal is to have the control suppress a certain custom property from a model and show the custom property from its corresponding drawing when the checkbox is checked. And i would like the unchecked control to do the opposite. They both are part descriptions that show up in my title block, and I figured the easiest way to have it set up in the drawing is to have both links in the same piece of text in the block. Is this possible?
