Unfortunately this is not going to work.  We have 1,700 picks that would need to be updated this way.  Each time we do this QB stops working while it does a re-fresh to the pick list.  That refresh takes about two minutes!  (and before you ask - we have powerful computers, running the latest windows software - so its not the computer).   And if we are unlucky QB will crash.   so for that reason your solution will not work.
