Hey @martha.rudkin!
I announced the new Budget Rollup report on May 5th. We are still sorting through the best way to share things. Sorry if you missed it.
Unfortunately, the approach above for customizing the report template will not work for hiding rows. (The approach above only extends the auto-generated report body with ARRAYFORMULA() lookups around the margins— it can add but can’t remove data.)
I’d need to modify the report-generating code to do what you want. That said, it’s not a HUGE project so I’ll add it to my list.
Thanks!
Randy
