Excel 3D Maps - Speedometer or similar funcationality

[Gift2women]

I'm brand new to 3D Maps in Excel, but have found them to be quite useful, though limited. I have Lat/Lon coordinates over time, but I also want to include some sort of Speed overlay that would show up when I use Create Video. (I have the Data Cards showing the data I am looking for, but that doesn't help when the video is captured.) In the upper left corner, the Date & Time is displayed and this, of course, changes as each dot on the map is moving ... I was hoping there was a way to do this with another Field as well, that field is Speed. If I could use some sort of Speedometer that would be 100, but I'm happy with just an annotation or some other way to display the speed changing over time. Any ideas?

Thank you.
