Load multiple selections at same time in Photoshop

Currently, in PS, the user can only load one selection at a time.  So, if you want to load, say, two selected areas, you need to use Load selection twice, with the second one having, for example, an "Add to Selection" operation.  This would be made a lot easier, if, for example, the Ctrl key could be activated to selected multiple items from the saved selection list. 

An even better facility would be the ability to load combinations of selections using any of the currently available operations assigned to any of the individual named selections in the available list - in this way, for example, it would be possible to load Selection #1 with a plus sign and Selection #2 with a negative sign - to load Selection #1  minus Selection #2.  This would be much quicker than the current approach which requires the second load selection to use a "Subtract from Selection" operation.   It would also allow, say, 3 or more named selections to be quickly loaded in one operation, rather than currently which requires the same number of "Load Selection" operations to be performed.
