Scatter correctly remembering guests when copying to other projects

Currently,
whenever you have a Scatter Geometry made, if you copy that geometry to another scene it does not remember the Guests that are assigned to the orgininal. So every time you copy that scatter to another project, you have to manually add them again ,and assign them a probality number.
In my project I'm using a greenery wall with over 35 guests wich makes it very tedious to reassign. How about you let them still be in the guest list, but mention the guests in the list are missing, so you can reassign them ( a bit like the File Path Editor) or skp auto finds them whenever you add the guests again to the project and refresh the scatter.

Thx
