How to add a pickup bar

Would it be possible to use the same syntax for pickups that the Bar popover uses for inserting or deleting beats? E.g. 4/4,1q for a quarter note pickup in 4/4? I don’t have any serious trouble with pickups in Dorico anymore, but it did take several trips to the manual at the beginning, and I still have to think hard to come up with the appropriate fraction. Syntax that reflects actual note values would lubricate the process for me, and might help beginners catch on quicker.
