Logic return Procedure condition for "Open Bound GUI with right click"

In the Block mod element, there's a checkbox that could easily be a condition that you insert logic return procedure in.

The image below shows the "Open bound GUI on right click" screenshot a checkbox.

I looked through the generated code within the "*Block.java" file and saw that it should be possible to change the fixed checkbox to allow you to insert logic return procedures.

Can't this have an if statement that will open the GUI when right-clicked only if a specific condition from a procedure is met?
