Dynamic title for shinydashboard(Plus)

When I define the ui for my shinydashBoardPlus app, I can define a title:

ui <- shinydashboardPlus::dashboardPage(
    header=shinydashboardPlus::dashboardHeader(title="My App", 
    ...

However, I would like to use the space right to the Hamburger menu for dynamically set text (e.g. the current work modus). Like this:

I would like this because I have several tabs that work on the same "group", so I can not include this information in the tab itself.

Is that possible and how?
