different roundings when ordering in PO

hello all

I have a requirement which I believe is not possible in SAP standard but is worth a try.

We have rolls of Pipes as follows:

10M

20M

50M

the requirement: when the quantity is 41+M, a roll of 50M should be ordered (and that is easy)

the problem starts when we need for example 71 M, it should be ordered as 50M+20M+10M

is there a way to achieve this?
