F1 lookup to remove text in search field after Major VMRS Code selection

We noticed that, when creating a wo line, in the F1 lookup feature for the VMRS Code selection, the mechanic would type in a key word to find his major code. When selecting his major code, the minor code list appears and the text previously entered remains, making the list shorter do to the text entry. This would be nice not to have any text inside the search field in order to see all minor codes.
