HowTo add new src repository on mai n project stream

Hello experts,

I have a stream thus:

ePIMS
...
ePIMS Team Stream (ePIMS Team)
biz.epims.reg Component (1: Initial Baseline)

My Repository Workspaces
St Clair on ePIMS (biz.epims.reg )
biz.epims.reg Component

Now I would like to add the component biz.epims.appointments to a new workspace repository within the ePIMS Stream as this component is just a module for the ePIMS project.

How do I perform this process?
