A great feature to add would be "batch deleting". The solution you mentioned is great, I'm glad it is not a feature now.  However, it doesn't' work good for larger PO's.  For instance, I have a 60 line PO, and 10 lines ship, that leaves me with 50 lines to delete one by one.  With double the clicks for the warning button (100 clicks for this invoice).  Say 10 more lines ship out, that leave 40 lines to delete (80 clicks), and for forth.  Painful.

The "Clear All" button removes the information of the lines I'd like to keep in there.  So then we need to copy and paste to a holding location, then re-enter the lines after the clear all is executed.  Also, this breaks the link to the original PO, so we have to do another step to go into the PO and "close" the individual lines.  Now the PO shows the line closed, but still shows zero as received, as the link was broken.  

So need a batch feature where we can just click multiple check boxes and select and remove them or unlink them at one time.  

Thanks for your assistance and support.
