Can you include the requestor into an AME approval chain?

Requirement is this:-

1. The requisition will contain smart form fields / information templates, that are completed and filled in by a series of different people.

2. The requisition is created and AME will automatically generate a list of approvers (eg. financial or category specific)

3. in order to complete all of the smart forms fields (requestor will not know them all at the beginning) - the requestor will manually insert new approvers before the system generated AME approvers. (Via Manage approvals)

4. The requisition is submitted to the new/manual people to help complete all the fields, prior to being submitted to the actual AME system generated approvals.
