Embedding/Nesting workflows


I searched the site and forums but did not find an answer.  Say you have a workflow A which captures some functionality.  Say you then have a workflow B which needs to re-use workflow A in a number of places.  Ideally you would want to be able to embed A in B, or have a way to call out to A from B.

I know about metanodes but the problem with them is that they duplicate the nodes inside them.  This means that if you want to change something in the metanode logic you have to change it everywhere the metanode occurs.

I suspect nesting of workflows is not possible, but it would be good to know if its on the roadmap?



I guess its either a trivial question or a very hard one? :)
