Annoying Github Powerup attachments

[JoJ3o]

I'm using Trello's Github powerup to link pullrequests to my User Story cards in Trello. This works amazing.

However I also keep track of sources I've used in the comments of the Trello cards. This also works well for me, but the Github powerup adds something I find very annoying.

All links to github (issues, discussions, code highlights) get an attachment thing under the comment, like this:

This gets very bloated especially with multiple comments and multiple code highlights from the same pull request:

Is there a way for me:

- to turn this off

- or to submit a feature request/issue somewhere.?
