Merge Schedule Rows with Dynamo

Hello everyone. I wonder is it possible to merge some schedule rows in Dynamo? I tried to do this with Revit but no result.
I tried to explain it with image below.
I would appreciate any advice.

I don’t think that’s possible. You can use Dynamo to export the same data to Excel and do the formatting there.

Thanks Einar, but I don’t like export to Excel. The schedule will be used in Revit Sheet.
