Ability to Select multiple spaces when Mass Updating Space Rates

While using the feature to Mass update space rates, it worked as intended but it was a bit cumbersome to get through. I select the Site/Space Type but when I am selecting the spaces, I have to select the space 1 at a time.

It would make the feature easier to utilize if when selecting the spaces, if you were allowed to select more than 1 at a time. Something hold Ctrl on the keyboard while selecting spaces allows you to select multiple spaces at once
