I'm trying to implement a property manager page for a macro I've been working on.  The macro increments a dimension to get a selected body at a specified volume.  So for my property manager page I was going to setup two selection boxes.  One for the dimension and one for the body.

The problem is when I add a selection box to the property manager the dimensions no longer show when you double click a feature in the tree or on the part.   This makes it impossible to drill down to a dimension to add it to a selection box.   If I don't have a selection box in in the property manager then you can double click on features or in the feature tree and it shows the dimensions like normal.

Any ideas how I can fix this?
