Hi there, @Petar_Dietrich 
I’ve reached out to the devs, and with their current workload, we don’t have any specific plans to roll out this feature just yet. I am sorry!
I’ve still added it to the Wishlist, though! If it gets enough votes, we might be able to prioritize it sooner. You can see the idea here: Add a counter for test messages in dashboard.
We’ll keep you in the loop and update you in the Wishlist thread if anything changes.
