Same thing here, unfortunately this is currently not possible. I have requested this in the Telegram group (August 30th) with additional ideas to have more than just one red bullet.
The "Left-Hand"-request ist also mentioned here https://github.com/HelloVolla/android-l ... /issues/92
so I think the developers have it on the list.
Keep the fingers crossed that they will notice the request and it will make to one of the next releases.
