Signatures reminder email

We currently have the option to add multiple wording options for Signature reminder emails.  However, there is no way to select which reminder email wording you want.  Whatever is selected as the default at the time the reminder goes out is the wording that is used. There really is no point in creating other wording because then you have to manually change the default, push a reminder (defeating the purpose of automatic reminders), and then change it back.  I would like the feature to select the wording to be used on the reminder email wording at the time the Signature request is sent.
