Repeating Values from Previous Row in a ReportModel

I have a row of data where the header info only exists on the first row, How can I extract this data and repeat on all the other lines below? If I choose a header region and extract it, then create a date region, it captures all but the first row., I assume this is because it can’t use a row as a header and data.?
I could ignore the fact that the top row was a header and treat it solely as data and then fill down in Excel, but I have loads of accounts and it would be great if I could find a workaround for this in Astera ReportMiner.

You can create a data field by selecting the header info, right-clicking on it, and selecting Add Data Field. Then, go to the Field Properties and set the value of Value if Null option to Use From Previous Record from the drop-down.
