Document Style Selection on Auto Generated Purchase Orders

Summary:

We would like to understand any options available to selectively route requisitions to either auto-PO creation or to buyer queue based on a dollar amount so that buyer can specify document style other than standard when applicable.

Content (please ensure you mask any confidential information):

Once approved, our requisitions are automatically converted to Purchase Orders. However, we would like to create a condition that say, if a requisition is over $XX amount, it should instead go to the buyer queue to process these to PO so that they can select the appropriate Document Style (e.g. complex purchase order template) and anything under $XX should follow auto-creation process and pick the standard style. Is this possible?
