Using a folder with files with different structure

I created a dashboard that uses files of different structures: Sales metrics, Ads metrics...

And whenever I want to show this dashboard to another customer, I need to manually change the path of each of the queries, which is very time consumming,

Is there a way to import the folder where all these different structure files are and then reference the source path of the queries to its corresponding file within the imported folder, so everytime I change the customer I just change the path of the folder?

Thanks
