Guarantee facing direction of jigsaw structure.

I am making a pack which adds long barrows from the neolithic period. These have a wider east entrance and a narrow west entrance, and bodies were buried with their head on the west side facing east.
Running /place as a placeholder entity makes sense, but is there a less performance heavy method than running the function each tick?
Is there a known guide or reference for this technique?

Thanks!

You could schedule it to be less often than every tick, but otherwise no, you're going to need some kind of repeated check to find that entity and make it run the command

The performance impact really should be very negligible if you're using target selectors right
