Is there any way to save grids/row/columns down as report objects to be reused?

Summary

How do you simplify the maintenance of report grids/rows/columns on multiple reports in MR?

Hi there

We are heavy into build a large number of similar styled reports in Management Reports within Narrative Reporting. 

I know this used to be a function in HFR but cant seem to see any doco or function to be able to save/reuse report objects on different management reports.

The challenge we have is that when we have a set format like a P&L structure or a MTH/YTD structure across 10 reports, when we have to add a new line, we have to do it 10 times.
