Using lscm to set component baselines on a stream with no stream reference

Here's the scenario: I created a snapshot on a workspace with baselines so now all the components of that stream have a baseline "baseline1".  Then the snapshot is deleted.  Now I want to reconfigure a stream using all these component baselines (all named "baseline1").  How would I go about using lscm set component for that?  The arguments for set component:

 target-workspace - The target workspace or stream to change. To specify the
                     workspace or stream, use its name[@repo], alias, or
                     UUID[@repo].
  replace-type     - Source item type. One of: "workspace", "stream",
                     "snapshot" or "historyRef"
  replace-source   - Source of the new components. This item must be of type
                     specified in replace-type. To specify an item, use its
                     name[@repo], alias or UUID[@repo].
  components       - Components to replace. To specify a component, use its
                     name, alias or UUID.
    

I have a target stream but replace-type is not a workspace, stream, or snapshot.  It's just a baseline for the component.  I'm not sure how to use historyRef - is that what I'm looking for?

I had to do this with the UI because I couldn't figure out the right syntax to do it from the command line but am still interested to know how I would set a component baseline into a stream when no other stream, snapshot, or workspace is using the baseline that I want to set.
