The Garmin FR10 running watch has 2 screens to display data when you run. Each of these screens can, in turn, display 2 data fields.
During a run, you can scroll thru these two screens, plus time and date screen, using the lower right button on the watch. In this way, the watch can display up to 4 data fields while you run.
On a different setting option, you can set Pace to be average pace or instantaneous pace (default). This setting is absolute, you cannot have 2 pace data fields, one for average and another one for instantaneous.
Having set the two display screens already, including (now average) pace, you have the option to include instantaneous pace as well.
Just turn on Virtual Pace. This feature takes a pace given and informs you if you are ahead or behind it.
Now, as you run, you can scroll thru these screens with the Virtual Pace screen now displaying a fifth data field.
