Using RelativePath in base URL for scheduled refresh

Hello Power BI Community,

I am trying to combine the tables from each of the following with different domain names but similar data:

www.a.com/foo/table/

www.b.com/foot/table/

www.c.com/foo/table/

I know scheduled refresh does not work with dynamic URLs, so using a parameter:

Source = Web.BrowserContents("https://www." & DomainNameParameter & ".com/foo/table/") will not allow me to do a scheduled refresh.

I've seen good solutions to this when modifying anything after the base URL with RelativePath as explained in this post by Chris Webb. But the RelativePath workaround only works after the base URL.

So something like:

doesn't work, correct? 

Is there some approach I can use in order to use a dynamic URL in the base URL, or am I stuck having to refresh this dataset manually? 😞

Any help you can provide would be very much appreciated. Thank you!
