Hi everyone!

I need to place L shape solid rail to my base cabinet, but I wish for my cutouts to be only pockets instead of full corner/panel cutouts. 

But as I was looking for those cutouts settings, I find myself unable to find any part that they might be coming from. I looked everywhere that I thought about: (product, subassembly, part properties, design data, and workbook designer), to no avail. Either I'm blind or they are really really good at hiding and/or inaccessible.

I know I could put dowels instead, and that's probably what I'll end up doing. But knowing Microvellum, it would be weird to not be able to access those data and it's driving me mad! (Jokes... :)) 

Anyone who could help me find those? 

Thanks again!
