WP Time Capsule - set (restore window) options per group basis

I want to be able to set the restore window (wptc_revision_limit) on a per client group basis as our maintenance plans provide different restore windows.

One thing I’ve had trouble with – Bulk settings manager does not work with their options when trying to create a key.

I like design of the “Maintenance” extension’s scheduling feature. You set your options, then select the client group or site for it to apply to.

If there is some way to bulk manage the WPTC options across multiple sites (all i want to do right now is change the restore window days) that would be great.
