Load data from Power BI dataset into Datamart

Hi team.

I have report which is pulling data from multiple sources including other Power BI reports.

I created direct query to other Power BI datasets but since recently they are falling down.

Memory issues, tables are not found and etc.

So I was thinking I can may be create a datamart and pull data there and then connect it to my report.

Unfortunately I cant find an option to use Power BI data set as a source.

Any thoughts please?

Thank you.
