How to set the status of Shipment Line to Interfaced using API?

Summary:

Content (required):

When a Supplier Returns Without Receipt transaction is created with 'Physical Material Return Required' checkbox enabled, a shipment line is created with Line Status as Staged, and Interface status as 'Ready to Interface'

Our aim is to interface this shipment line to external WMS while doing so we want to change the Interface status to 'Interfaced' as soons as the integration picks the file, so that next time the same shipment line will not be interfaced again?

How can we achieve this?Which API can be used?

In case of SO or TO based shipment lines there is API called Generateshipmentrequest but it works on the request payload parameter 'Pickwavenumber' but in case of returns there will not be any picking process hence the pickwave number cannot be generated for the returns.
