ok, I found where the physical portal control is located within region:
ex: HH/TT
Code:
[trans]
131 1 60
-2708.798096, 404.276001, 1185.218994
5.000000, 5.000000, 5.000000
-477.000000, 131.000000, 475.000000
I am presuming
[trans] = tells it the following is transport info
131 1 60 = WORLD ID TAG TO / WORLD ID TAG FROM / LV REQ
(IDK why HH/TT is 1 60; when every other [trans] is 1 0)
-2708.798096, 404.276001, 1185.218994 = this line tells it the cords to teleport from the map (in which this region file is for)
5.000000, 5.000000, 5.000000 = this I am guessing is the range for which the transport area works (how far outside of the above number)
-477.000000, 131.000000, 475.000000 = this line tells it where to take you inside the new location
I cannot yet figure out how to add/remove the blue ring (I am trying to learn based off of the above example since the ring already exists for HH/TT) :\
