Single Form accessing Multiple Backends

[jsccorps]

Currently have a form for a single backend (e.g., Backend A). Client wants
to add a new region/account and use the same form to access the data (Backend
B). He wants the customer relations folk to be able to go between Backend A
and Backend B (e.g., switch back and forth). That is using the same form,
access the Backend A data and the Backend B data. Would I need to link the
form to the requested Backend - if so , how would this be done? Or, is there
a better way?

Or, is there a better way?
Yes, use only one backend but add a new field to distinguish the data A or B.
On form use Option Group to select A or B. Option Group selection used in
query feeding form as criteria. Refresh following Option Group change.
