I've noticed their is no way to assign customers into specific groups which you could then assign a scheduled transaction for the group rather than needing to schedule a task for each customer.

It would also be nice to have mass invoicing where you could print invoices for anyone that has a balance in in a specific group or what not.

Lets assume I have a business where I have 400+ customers of which some are billed monthly, some quarterly and a few yearly.  When gnucash lets me know my monthly billing has been done I can merely click on the group to print all my invoices without printing invoices for the quarterly or yearly customers again.

I can think of many businesses that would benefit from this functionality and would love to see it introduced in the future.

At this time I would like to thank all the developers for their time in creating/maintaining this great product.
