Different Lot size for same material

hello,

I would like to know if it is possible to customize system to have different lot sizes/rounding quantities for a same material depending on the vendor ?

Scenario is : company have 2 different suppliers for the same ite, main supplier and backup.

The main supplier have no rounding quantity (can provide L4L quantities) but backup uses a process that produces batches of 10 an therefore the order must be a multiple of 10 when buying to this second vendor.
How to obtain 2 different rounding quantities for these suppliers ?

Thanks for your time

Regards

Morgan
