Import / Export visuals and measures

Is there a way to import and export only the visuals and measures of a Power BI Desktop template? We're still working with excel and not yet ready to justify the costs of Premium. 

The data source is a downloadable excel sheet that contains data on which date the user chooses, and the fields are always the same. So I simply need Power BI to accept the new data and repopulate the visuals. I think the measures is associated with the tables so I could understand if this would be tricky. Currently, when I import a template, it imports everything and the only thing I don't want is the raw data.
