Check if player in Region without Volume

Hi,

How can i check if the player enters a specific area of the map without placing volumes in the level.
I have a data table like this:
X1, Y1, Z1, X2, Y2, Z2, regionName

-13588, 293949, 24, 120, 20202, 24, middleSouthWestPark

Inside this table stored “zones” of my map.

X1, Y1, Z1
The bottom left corner of the zone

X2, Y2, Z2
The top right corner of the zone

I have 120 of these zones. So it would be a pain to create manually for each zone an trigger volume to check if player is inside it. Is there a solution to check this only via code? I dont think that this is impossible.

I need this to Display thr name of the zone on the screen and to control other things like sounds.
