I believe the next iteration 0.7.0 will allow more configuration when importing from RR - the unfortunate part is the mpscs database has no uniformity to the data or cleanliness of the formatting - you’ll forever need to manually update all of your settings and talkgroups if you’re concerned about continuity.
If you’ve made it this far down the rabbit hole, altering the site from “Control” to “Wayne County Simulcast” or “Macomb County Simulcast” or “Oakland County Simulcast” should be straightforward, do it once per site and you’re good to go. Easy Peasy
When importing sites from RRDB, I wish the "name" field was actually filled in with a name! Counties like Wayne have multiple sites, but the unique description is replaced with "control". This is super confusing to deal with. The value could just be "Site Description - Control".
