[REQUEST] - Constrained by wall but for EFFECTS

[KingFliren]

I started using and making some macros to add some interesting effects to characters, both players and npcs, however i noticed that these effects are visible through walls, which feels like a shame and a little bit annoying.

What I would like
A command for effects to be visible or not through walls, like the already existing .constrainedByWalls but also for effects, maybe alternatives as .aboveWalls etc... with a configurable boolean and maybe some options that depends on the type of visibility the wall provides.

Alternatives
Outside of what I've already explained, I don't think there are other alternatives.

Additional context
To add to this, due to the system I am playing, it would be neat if this feature is also compatible with V11
