Add a Select Folder option for Generate Overview Pages from Domain Model

Being able to generate pages from the Domain Model is a very helpful feature and saves a lot of time.
Only, every time you call it it will create another OverviewPages folder and starts numbering the next ones as -_2 and -_3 etc.
It would be great if you can select a folder where you want to store the generated pages, allowing you to place them directly in the right folder or in a scratch folder if you want to use parts from the generated pages.
