For versions of BST prior to v4.24

The RecurSched Template now has a drop-in template called RecurSchedUpd that you can add to your existing apps to support updating and deleting by date-range features for recurring appointments.

The updated RecurSched template includes the Update button and Checkbox, and they can be safely deleted if you do not want to use this feature.

Look at the 2 screen shots below.
