Editing the schedule attachment schedule

I was wondering if anyone knows of a way to edit the scheduled attachment?

Have set up "send as attachment" under file a portion of the sheet. This is scheduled to go with specific formatting, message and a group of people on specific date/time for a period of time. Is there a way to actually change this without having to redo it? I can edit the recurrence, but not the people it is sending to, the format of the data nor the message used when sending the attachment.

I love the function to send a "monthly" update to a group of folks, but when I need to change or add the list of people, I have to start all over. Maybe I'm missing something, but thought I'd check with the SMEs.

TYIA ... :)
