Supplier has different Remi-to-Address

Content

Hi 

We have below requirement in our project -

- We are printing check with Supplier address on it.

- Supplier has 2 different addresses, one is for Purchasing/Procurement and other is for remit-to (payment)

- Now, how can i print the remit-to address on check ?

- Should i create 2 sites, one site will be used for PO and other will be for payment then how would i be able to match the PO with Invoice as site will be different. 

- Please suggest some option to achieve the same.

Thanks in advance !
