CreateQuickInvoices template 25B multiple errors with copying of contents

Summary:

When invoice details with 40+ lines are copied against one header invoice, we had multiple errors and are hard to troubleshoot.

1. User did copy the account distributions at two columns instead of selecting individual segment values at each line. as this is a quick invoice template, it shouldn't be like you select 80 values each with 7 segments. Template gave us issues when the concatenated value is copied vs selecting individually which takes more time and is not Quick.
2. User could not use the same template each time, Issue with session disconnect each time an error is out. User has to get the template again before working all over which took most of the time.
