[GUI] unit - unit within range of cant take points?

[Matthew's_warcraft_book]

I need an event for when a unit comes within range of a point (variable), but the variable isn't showing up, only unit variables. How can I do this? I will be replicating this trigger dozens of times, I'd rather not use regions for every single one, is there another way? I am open to using jass if thats the only way. Thanks for any help!

This is all I can really think of as possible options:

1) You can use this Event with a Unit instead of a Point, like a pre-placed locust Unit (dummy).
2) Regions (this is what they're used for after all).
3) Use Timers to periodically check if units are near the points.

Thank you! I think I will end up using regions, its gonna be a mess though haha
