Pragma on a stage or on the entire schedule

I read this post Adding a pragma onto a schedule and have a slightly different use case.

I want to put a pragma on a stage. Every leaf IterVar in the stage is tensorized. But I still want to use pragma to annotate the stage with some information. What’s the best way to do that?

I may also need a pragma for the entire schedule to instruct the compiler to run experimental implementation.

My current workaround is add these information to another stage’s leaf IterVar. Any better solution is appreicated.
