Support subdomains as a part of TreeView

Proxyman 2.3.0 on macOS 10.15.5

Sometimes domain names use randomized or unique prefixes e.g.
a1b2c3.cdn.global.com or territory.country.site.com. They are often used for either some location-related or endpoint-related ID, which could be anything from an Amazon data center to a network rack.
There should be some way to group them all together. Adding each of them into pins one by one is not productive.

Existing behaviour (two pins are added by hand):

Pins
  a3b4c5.cdn.global.com
  ca.us.site.com
Apps
Domains
  a1b2c3.cdn.global.com
  a2b3c4.cdn.global.com
  a3b4c5.cdn.global.com
  a4b5c6.cdn.global.com
  ca.us.site.com
  wa.us.site.com
  ge.eu.site.com

Expected behavior (two pins are added by hand):

Pins
  *.cdn.global.com
    a1b2c3.cdn.global.com
    a2b3c4.cdn.global.com
    a3b4c5.cdn.global.com
    a4b5c6.cdn.global.com
  *.site.com
    *.us.site.com
      ca.us.site.com
      wa.us.site.com
    *.eu.site.com
      ge.eu.site.com
Apps
Domains

I think the expectation is that I can run some kind of search against domain name/path and store the results as a "smart pin". And it would be double-cool if multiple-level domains could be supported.
