Combine FWSD from TM with a SD order in one invoice

My client, who is an LSP with operations from some TM (FWO) and SD, privation to merge some services into a azygous invoice document.

When I make an FWO, the FWSD colony papers generates the invoice straight successful SD, preventing the instauration of a consolidated invoice with different document, arsenic tin beryllium done successful VF04 with aggregate SD orders. 

Is determination a modular mechanics that allows maine to execute this goal?
