AME approval for TDS invoices

Hi,
We have enabled AME approvals for Invoices. By default approvals are required even for TDS Invoices & Credit Memos.

Client is requesting to remove the approvals for TDS Invoices & credit memos.

We have modified the AME setup by enabling Auto Approval for the Invoice_source='INDIA TDS'.
Even after modifying this, we need to enable the 'Initiate Approval' in the invoice screen, upon 'OK', the approval status of Invoice changes to 'Approval Not Required'.

Is there any way to change the Approval Status to 'Approval Not Required' without initiating the approval.

Thanks in Advance.
Amar
