It would be nice to be able to save work on a workflow task for completion at a later time.

For instance, when filling out GL account information on an invoice with a lot of line items, it would be nice to be able to save the progress to be completed later. Let's say I have an invoice with 50 line items that all need to be coded to a different account. Maybe I get to line 30 and need to go to a meeting. There isn't any way to save my progress so I can finish later.
