Refreshing multiple files with single authentication

One dataset can contain queries from multiple data (CSV) files stored on the same OneDrive for Business account. On scheduling data refresh you need to log in for every single data file, not just once for the whole ODfB storage account. Would it be possible to accomplish this with a single login? Then the query could just navigate to the CSV file instead. It works fine in case of Azure Blob Storage, for example. But we cannot store the CSV files there for other reasons.
