GRN number allocation - reg

Dear friends,

We are facing the problem on the GRN number allocation.

Presently we are having 3 legal entities (Companies) and approx 20 Plants. We are facing an issue on GRN numbers getting allocated across the group. (Eg GRN No #1 allocated to Plant I which belongs to Company A and GRN No #2 is allocated to Plant II which belongs to Company C).

Auditors are insisting on the GRN number based on plant or atleast for a legal entity (company).

Is there any feasibility to configure the GRN number range based on company / plant.
