Shape Maps and titles

Hi,

Fairly new to power BI.

I have a report with a number of linked visualisations including a shape map of my City split into different suburbs.

I've set up a card as a report title which displays the name of the suburb which is highlighted in the shape map. Is there any way of showing City Name when no suburbs are highlighted on the map? Currently if nothing is selected on the map it defaults to the first suburb name. Or is there another way of achieving this?

Thanks
