[galaxy-dev] Using workflows as components in workflows?

Hi there Is there a way in Galaxy to use workflows as components in workflows? I've got two datasets that start as Genbank files and are processed (features extracted, translated to AA) by a small workflow, and then BLASTed against one another. Ideally I'd like to modularise the initial steps as a workflow so that I can say input data goes through this workflow and then the result is fed into either the query or the subject slot of blastp. So is this possible? Thanks! Peter
