How to compare traffic of subdomains in a report?

Question

Google Analytics

Hello. There are 40 affiliate subdomain sites and the main domain - Head Office. There is a problem with the analytics of such a group of sites.
1. I want to compare traffic and conversions in 1 (!) report, and not switch between profiles
2. I want to show the subdomain in the links of the content reports (now only the ending of the url) prntscr.com/7pt93g

Answer 1

Why is this not suitable ? How to set up a counter for subdomain analytics? ?

Answer 2

The subdomain will be written to the dimension host. Try to display this dimension in the report.
Or you need to create a copy of the view and set up a filter in it so that both the relative address and host are written to the page address.
