9.1 Requisition Self Service Approvals w/MultiCurrency setup and process question

 I am looking for some information on 9.1 RSS Approval processes in a multi-currency environment.  Basically the situation/requirements are as follows:

Let’s say I am authorized to enter Requisitions for different B/P’s, say USD B/P and HKD B/P.

My approver is Bob, and my Approval levels are setup at $50,000 USD for the first level.  (Note: There does not appear to be a way to setup approvals by currency.)

Let’s say I enter a HKD B/P Req. for 310,000 HKD which converts to approx. $40,000 USD.   Based on how the E1 Req’s work, this would get routed for approval even though I am authorized for up to $50,000 USD, would it not?
