Property Set: join existing properties into same report

[nekromoff]

Use case:
Having existing property set (usually the same URL, but with the different protocols HTTP and HTTPS) means I have two separate reports for each URL (HTTP and HTTPS).

As it is possible to join these websites under one property set and get overall report, I should be able to join these in O-S-A as well.

A proposed solution is to merge the data in the reports for the same URL, just different protocol used. Alternative solution is to offer both separately as well as automatically joined (as another option).
