Power BI querry supporting with another same data base

[u4unnicool]

I have a dash board which runs on power querry to display a specific dashboard please find the image to see the queries

You can see there is two data source one is ipeds1 and second IPEDS1 Both the data source are same nature and type we do left outer and right anti on this data and appended it together for specific year for example 2019 now in 2020 another data will be genrated which we have to add to current dash board how we can add the other data to exisitng dash board with same querry and exisitng dash board without creating a new one.

so that the slicer will have each year data reflected automatically the data source will be from share point folder excel files
