Alright, so this idea is similar to "Where are they now" by Kentington, "where are my provisioners" by drdanzel, and mainly "Tracking marker" by GovnoWriter and expands on them. (NexusMods)
Basically, you use a misc device (prop could be the Transponder or the Beacon from the Chinese Ghoul's Nukes), or even armor based device that must be equipped and drop it into an NPC's inventory. Each tracker could have its own number, similar to the Beacons from "Create Followers" by tofudwarf. You could even rename the item. Then, you can use a holotape to click witch trackers would become active as quest markers and witch are disabled, possibly showing the name for each beacon you set or just by number. Finally, you can click a beacon and teleport the NPC to you, and even make a group (maybe multiple groups) for teleporting multiple NPCs.
