Is it possible to ignore certain files from a pull request change list based on a some condition?

It might be a shot in the dark, but is it possible to ignore certain files in a pull request based on some condition? To illustrate, our team manages a relatively large monorepo, and sometimes when packages/files are moved or renamed, a lot of `import X from Y` statements change as a result. 

It would be nice if we could e.g. ignore files (from the PR change list) that conform to a particular regular expression, so we can focus on the files that contain “actual” changes.

I am aware that it is possible to view files of one specific commit of a PR, but I still wonder if the feature I described exists.
