I know theres a UI option in the data file. Not sure what it does or how it works. Is there a way to have it were it opens the ui and then can select where you want to go, for multiple spawn locations, and then txp you there on clicking the place?

the ui option is to have it display a message and click ok or cancel to do what you program the npc to do. you can use spawns DB and have the npc spawn you to one location on the map or set it to random to spawn random spot on the map. currently there is no option to set it to open the ui and select a location.
