Shimano di2 overlay data field

Hi all,

Although Di2 data fields are proprietary integrated to the Edge Series, the gear number is shown as a permanent data field, which for me is not necessary.

I am wondering whether there is a data field available that appear for a couple of seconds after a gear change (as an overlay). Such as the Ki2-app for the Karoo bike computer (https://github.com/valterc/ki2).

I have searched the IQ-store but couldn't find something similar. Is anybody aware of something like this?

thanks
