Is there a way to message patrons with lifetime pledges over $X?

I recently wanted to send a gift to all of my patrons who have, over the lifetime of their patronage, given me more than $X in total pledges. I could sort the member list by that column, but couldn’t find any way of actually messaging them all at once. In the end I just bit the bullet and sat there, clicking them all one by one, pasting the same message to all of them.

Did I just miss something obvious, or can you not do this?

Cheers,

Rich
