Set all flows in a document to just one flow

Hi,

I'm converting legacy docs to DITA. The conversion process is failing when there are multiple flows in a document. Even though I tried to set all the flows to the same flow using the menus in Framemaker, during the conversion process some rogues flows turn up. Many of the flows are often quite tricky to find.

Is there a script to set any all flows in a document to the same flow?

Thanks
