Can you add a check box or button in the Lean-To Configuration tab to indicate that it is going to be a verandah and code it so it doesn't drop out all of the openings, please? Perhaps under the 'Include' line & check box? (Rather than right clicking on the layout after the lean-to/verandah has erased all of the openings)

I'm constantly adding verandahs last in my quoting process for various reasons and after spending 10-30 minutes with a customer choosing all their window opening sizes along the walls, they decide to add a verandah and that drops out all of our openings on that side. Then I have to start the process again, which is difficult since the opening dimensions aren't indicated on the layout (or even on the plans!). If it was, I'd take a screenshot before adding the verandah so I could easily replace the openings.

Please? Cumulatively, I lose hours of my time adding openings back again, usually in front of customers.
