Change record selection from a record picker back to a dropdown.

Once you hit 1000 it will force the pop up Record Picker.
A solution is to make that be a Conditional drop down.  So the user would enter either a number from 0 to 9 and then see a list of bar codes beginning with that number (ie 1/10th of the 1000 records),  or if the bar codes have product names, then they could enter a-z and see, for example just the T's.
