[Remind-Fans] Using BEFORE/AFTER to adjust by more than one day?

[Tim Chase]

I have several events that fall on the Nth weekday of the (e.g 1st
Saturday) and when they get bumped by an OMIT, they usually move back
one week (so instead of July 4th of 2020, it would move to July 11th
of 2020).  Is there a way to specify that the BEFORE/AFTER should
shift things by a certain number of days other than one?

Thanks!
