Hi v-kelly-msft , thanks for the reference.  This put me down a path of reviewing maxx and it looked like what I was seeking blogenterprisedna had documentation for.  

https://blog.enterprisedna.co/using-the-maxx-dax-function-in-power-bi-to-calculate-recent-values-in-your-data/

For those not wanting to click on the url the solution is:

Max Date = 

VAR CurrentName = 'Dataset'[Name] 

RETURN

MAXX(

   FILTER( ALL('Dataset'), 'Dataset'[Name] = CurrentName ) , 

     'Dataset'[Date Taken]')

Then placing Max Date in the legend.  

Thanks Again!
