PowerBI filename and path

Hi - I have a number of client folders each containing a pbix file. The pbix is in turn linked to a data source file (.xlsx) located in the same folder as the pbix. All pbix files are identical and the source files are also of identical format.

Currently when I set up a new client folder I have to open the pbix and update a parameter so that it pulls in data into the current folder. This works but is manual and therefore not ideal.

Is there a way my pbix can identify its own path/location? then I can just set up the data source in the pbix to be /localfolder/standarddatafile.xlsx

(I know Excel has a simple VBA function that does this i.e. SourceFilename = ThisWorkbook.FullName. So maybe not a stretch of the imagination for PowerBI to do the same)

Any help would be appreciated

Thank you
