Is it possible to enable a trigger box with another trigger box?

[BladeMaster (Parth Naik)]

This is how I did it:
Setup:
I have 2 trigger boxes in my level, named TriggerBox and TriggerBox2. TriggerBox2 is initially disabled by doing the following in the collision settings of it.

I have the following setup in my level blueprint. Once the FPS character goes through TriggerBox, it enables TriggerBox2.

Hope this solves your problem!
