Venu 3 and Edge 520 plus

Hi all. First time writer.

I just got a Venu 3 and it has been great.

I cycle for exercise using an Edge 520 plus, wahoo speed/cadence and an external HR monitor. My goal was to use the watch to display some more data while on my rides. Maybe even having fewer data fields on the Edge so the text will be bigger, placing others on the watch.

I just learned that the Venu doesn’t do extended screen.

So, my question is: what options do I have with visual data when I ride using both devices.

My plan was to have HR stats and/or cadence stats on my watch, while having and have speed/time on the Edge, but it seems like they won’t talk. It seems like I only can broadcast current HR through the Venu to the Edge

Any creative thoughts on what data I can have on my watch and edge. 

Thanks
