I would like to use a spreadsheet to select the invoices in which I am paying.

At this time we use Event one writeable and it would be more convienient to go in and change or click those invoices in which I am paying, then send to Sage to set up for payment.  This would only work if you are paying the invoice in full, I don't believe it would work for partial payments or retainainge.

Thank you

Rhonda
