'New' feature label

Hi all,

My team periodically updates our dashboards (used by other internal colleagues) with new features, visualisations, etc. 

I was wondering if there was an easy way for the dashboard to highlight/alert users to any new features, visualisations, pages etc. between published versions. 

It could be as simple as having a 'new' tag hovering somewhere around a visualisation/page. I thought this might be possible but after searching the web have not found a solution. I could, of course, create a tile/text box and paste it near any new features but this would be quite labour intensive (incl. removing the tile/text box/image once a new version was published). 

Any help/suggestions would be greatly appreciated.   

Thanks,

Jamie
