Option to combine Invoices directly.

Add an option to combine Invoices directly. We have a group who is being invoiced separately for each date of use. We want all events by that group to automatically be placed on the same invoice. There should be a way to make this happen automatically or a way to check mark the dates from the list and combine into one invoice.

As of now, the only way is by 'voiding' one of the invoices. This will then allow you to transfer the requests to another Invoice. After that, go to the remaining Invoice, click on Actions, and select ‘Add Request.’ This will enable you to add any requests from the same group to the existing Invoice. This is double work for us.
