With all due respect, the number of days should clearly not be a static number.

There's no reason to not allow the account in question to choose the number of days themselves.

Also this function is disabled :(

Oh, if it can be coded as a dynamic number that would be the best of all. I was going under the assumption that would involve a decent amount of work and testing.

nah you could just add a variable to the operation:
days_to_reset
something like that.
would be really really easy imo.
