Requisition status need to change to 'In Process' as soon as submitted for approval

Hi Team, Currently we are facing an issue where user's are submitting the requisition for approval multiple times from I Procurement. The cause of this issue is the status of requisition which remains as 'Incomplete' for 3 mins. Our workflow background process is scheduled for every 3 mins. Due to status 'Incomplete', user gets confuse and try to submit it again for approval. Currently 'Workflow Background Process' is scheduled to run every 3 mins. But i could not see any option to schedule it in seconds. Could you please do let us know if there is any way to handle this problem ? Our requirement is, requisition status should get changed to 'In Process' as soon as it is submitted for approval.
