Is it Possible to bring 2 people picker in one dropdown in PowerApps?

Hi, It is possible. We cannot bind driectly multiple column to one dropdown ;however, we can create another column concatenating multiple column (your case two columns).

Visit below site for details.

It would be quite difficult to handle into single dropdown. Would you please share your purpose?
