Hi Lukas,
I probably won’t be able to add this in a future release, due to many complications, but with a custom code this should be possible without problems.
I constructed a possible solution for you, which should do the trick 🙂
Add this custom code to the functions.php in your theme/child theme directory. Before editing, please make sure to have a full site back-up just in case!
Let me know if you need help with this. After the change, the results should be outputted in a layout like this: https://i.imgur.com/vsgcN2r.png
I hope this helps.
