No Thanks Select All Option for Watched Threads

I started going through old watched threads and clearing them out.

I'm down to 68 pages from the 80 I started with, but there is no way to select them all -- you have to select each of them individually.

Is it possible to add a Select All check box?

EDIT - 9:00 PM PST: Made a typo. Can a staff member please remove the S in Options? c:

 

There's no way to do so unfortunately. It might come along in future XenForo versions but I doubt it's a highly demanded feature.
