Is this the reason why "Reclassifying multiple Transactions" doesn't work when trying to mass update products/services on a sales receipt?  Because when you change the product/service, it wipes out the rest of the info on that line?  

"Reclassifying transactions" never works for me when I'm trying to mass update the product/service within a sales receipt.  I have at least a couple hundred to update... and I'd rather not do it one by one, AND have to make sure the amount is re-entered correctly.  What a pain.  And it risks more error.
