Info record for Import conditions.

Dear all,

am using condition record for Import condition types. For that we have maintained access sequence and maintained conditions as item conditions. Now problem is if there are 20 items in PO, then for every line item there will be 6 Import conditions which shud be paid to Custom vendor. So user need to change it in every conditions at item level. SO he will need to change 20X5 = 100 conditiond for that PO. Is there any other possible solution for this? Is there any way that if we maintain Vendor in that condition type, all time it will jshow the same Cusom vendor there?

Thanks
