Part numbers specific to a customer?

Hi

We want to be able to show our own part number as well as the customers part number on the invoice. However, different customers have different part numbers for the same item.

Is there a way to link a part number to a specific customer? e.g. if customer A buys the product then that customer sees their part no. but if customer B buys the same item then their different part no. is shown. Is that possible to have sage input specific part numbers dependent on the customer we are invoicing?

Thanks
