Edit Trays Actually Planted

For some orders the total trays required is an overage like 3.6 trays and the system rightly tells me to plant 4 trays - but if the overage is small like 3.1 trays I’d like to be able to use my judgment and only plant 3 trays (especially if I know there’s a buffer built into that crop). Would it be possible to be able to edit the number of trays actually planted?
