Is there a way to prompt the user, upon opening a project, to select a workset?

I could have sworn that I read this somewhere not too long ago. I tried searching around but could not locate, perhaps it could be a add-in?

The idea is that you must choose a workset before doing any work to prevent accidentally working all day in the wrong workset.

To my knowledge you can only choose to specify which worksets are opened when opening a file (aka demand loading). I believe the 'default' workset is the last one set as default by the last user to exit the file i.e. the last 'remembered state'
