Select All Button for Scheduling Days on Batch Contacts

We'd like to request the addition of having a "select all" button added to
the batch setup that would tick all days of the week. We are currently
setting up a lot of batches and anticipate many more in the years to come.

If this were currently in place, this week alone, this enhancement would
decrease my keystrokes by 630 clicks (not counting the ones I miss clicked
and had to click a second or third time).
