Possible to change several clips at a time in multicam edit?

We have a multicam sequence with dozens of edits. We need to be able to change the camera on all of them instead of right-clicking on each one individually.

Yes, I know it would just take a few minutes to right-click on 50+ clips, but apparently this is on 30 different sequences, each over an hour. So it's going to take a long time to do it manually.

I've searched here and on the net to no avail. I tried selecting multiple clips and choosing MultiCam when right-clicked, but you can't change the camera on more than one clip at a time.

Any suggestions?
