Hi Fred - let me wish you a slightly belated welcome to the forums . . . .
Whilst I appreciate that the solution I'm about to suggest to you is not precisely the same as that used by Reciva, (Yes, I do also have a Reciva account), this will be on the way to solving your problem:
1. Go to "Add a stream" within the Volunteer Centre and add those stations individually that you consider as being your personal stations, (remember to make a note of their names!)
2. Once they've been approved you can then add these stations to your "Favourites" widget.
I hope this assists you
