How to write comment in Pull Request in file which is not shown due to Viewing limits?

[Michal Dachs]

Bitbucket started to limit diff view. see page: https://confluence.atlassian.com/bitbucket/limits-for-viewing-content-and-diffs-980465561.html

Unfortunately we used comments in Pull Request (diff view) for pointing the exact place where we see some problem during Code Review. How I can write a comment to the file which is now not shown in diff because of limitation (e.g. the Pull request contains more than 200 changed files)?
