Enable support for dynamic data sources in Power BI service

Unlike Power BI Desktop it appears that PBI Service doesn't yet support a refresh of datasets which are invoked using customer functions.

We have numerous reports that link to data held in sharepoint lists...each list has a unique name (stored against each row of data) and which needs to be evaluated at the time of refresh.

It works perfectly well in PBI Desktop but as soon as the report is published the functionality is lost.

The error is:
There was an error when processing the data in the dataset
You can't schedule refresh for this dataset because one or more sources currently don't support refresh
