Paginated/Report Builder: Subreport not retaining columns

[schavezenvision]

My subreport has 3 columns and my data is contained within a 5 inch rectangle; the data wraps from first to second to third column in the subreport.
When I call the subreport in my main report, the data continues along one long column - not retaining the original formatting.
I've tried Keep Together and limiting page size, but the data still continues along one long column.
Does anyone know how to keep column settings within a subreport?

This is a know limitation that is documented here: https://learn.microsoft.com/en-us/sql/reporting-services/report-design/pagination-in-reporting-servi...
