Yep, this is something I will have to change in the UI, because it is far for
being clear.

On the first screen, type the first letters of your existing project, and you
should have the existing one being "suggested". Just select it, and select
proper options on the next screen (possibly adjusting Scan Rules to widen the
mirror scope in your case)
