Can I put a select button on the header of this dashboard?

I have a dashboard using balsamiq, which having a list of doctors and I want to put them on the sider sorted alphabetically, and I want to display, for each doctor, different pages like Gestion de plannings/ Gestion d'activités et gestion de consignes.

It can be possible to put a select button, having the name of this page, on the header of this dashboard ?

Have you a suggestion ?
