Parts enhancement

I have my parts in Dev42 now, awesome, but 1 issue is I sometimes take  let’s say 6 cables, 2 blue, 2 white, 2 black, so to update the quantity, I  have to go into 6 records and update each one at a time, would be awesome if  you could make the Total count field editable from the first screen, and  change the values from that screen, or maybe put a + - arrow to increase or lower  the quantity’s. This would speed things up greatly. Thanks
