Dax Expression that only displays value for first in list

[bschil98]

I have a table of values that is comprised of names, dates, and a host of other fields. In numerous instances, the name will be tied to the same date while other columns are the differentiator. I am trying to create a calculated column that yields 1 if that is the first time the Name+date appear in the list. For all the subsequent times that name+date appears, I want it to return 0. Is this possible? Take the below screenshot as a reduced example:

@bschil98 

you can create an index column in PQ

then create a calucalted column

Column = 
VAR _last=maxx(FILTER('Table','Table'[name]=EARLIER('Table'[name])&&'Table'[date]=EARLIER('Table'[date])&&'Table'[Index]<EARLIER('Table'[Index])),'Table'[date])
return if (ISBLANK(_last),1,0)
