Adding Variables To Variable Watch

Hey everyone.

Quick question as the title suggests. In sure I'm overlooking something simple, but I can't figure it out. How do I add a permanent variable to the Variable watch control?

The reason I ask is that I'm using Roborealm for face/object recognition using a $RR_NV_AVR_OBJ_NAME[0] variable, but every time I close the project down and reopen it later, the above variable disappears from the list and I get a debug message saying variable not found (or words to that effect). So to get my recognition script to run, I have to show the camera a recognised object or face for the variable watch to catch it again, then I can use the script with no error messages. If I can add this variable as a permanent item in the watcher, it would solve the problem.

Thanks.
