Additional context

[manning-ncsa]

We already have the ability to upload a list of transients (new to the database or already existing) and (re)trigger workflows for the entire list. Is this issue talking about that, or is it about processing transients elsewhere and then importing the generated database records and transient file objects to a Blast instance? If it is the latter, what is the envisioned use case? And is that use case still relevant?
