Workflow feature Request - invoke from SuiteLet POST

I'm just getting stared with Workflows and it appears they are tightly coupled to records.  We use SuiteLets and Assistants for many operations here and the SuiteLet and Assistant are more than just a presentation of a record.  They have fields that are only used in processing the submitted form, fields from multiple related records, etc.

It would be cool if Workflows could be invoked from a SuiteLet or Assistant POST.  Maybe you could expose a new Custom Record option called "POST Sink" (or something).  You could define fields (and IDs) that correlate to the fields being posted from the SuiteLet or Assistant.  By using a construct like this you could let the WorkFlow system treat it pretty much like a regular record with the exception of event type filtering, saved searches, etc.
