How to add Service line to Transfer order

Summary:

We have a requirement to add service items to transfer order which would be non shippable lines. Our requirement is to use SCFO to generate intercompany AP/AR invoice with these service item line. Currently TO does not support adding service line, is there any other way to achieve this.

Thanks

Ninad.
