I think it can sometimes be useful if we can enable/disable the interchange for each loop, but I think there are a few things to consider if we introduce it, such as the behavior when the pragma is specified on a non-outermost loop. What do you think?

Yeah, I see the use case for that, I think that makes sense. And OpenMP6 for example, introduces a directive for interchange. Please propose a patch if you're interested in pursuing this.
