SSRS Subscription - Data Driven

hi 

Problem def - We have various branches and for each branch we have different approves (i.e. email address). I need to create a report subscription for each of these branches and send out report to their approves.

So should I create different subscription for each of these branches ? What the best way to handle this scenario?

I was thinking to create a SQL Job and let it feed different params (Branch codes, Email address etc) from a stored proc. 

Thanks for your responses in advance.

Cheers
