Capability of ignoring specific author's PRs, such as dependabot

[robrecord]

PLEASE:

Can you add the much requested feature of allowing us to filter out PRs from specific authors, or any other method to prevent bots such as dependabot from creating a stream of spam in our channels.

Please listen to the users! We are begging. As you may have seen in github comments, without this, the integration is annoying/unusable.

Many thanks.
