Vendors with multiple BACS

We have a requirement where a Vendor has different BACS accounts for different product sets we purchase from them.

Our problem stems from the fact that we have been taught we cannot have multiple BACS for a single Vendor and have to create new (duplicate) Vendor cards for each BACS. However, my purchasing team notice that when setting up a Vendor card, on the Payments tab the facility exists to enter more than one BACS account.

So my question: can you have more than one BACS account for a single Vendor and if so, how do we enable different ones against either a purchase order or direct invoice ?

Our platform is currently Microsoft Dynamics NAV 2009 R2 - version GB Dynamics NAV 6.0 R2
