Is there a way to copy just a single report sheet(s)- not the whole report from one report file to another that already contains report sheets.

I have similar companies (account numbers) in different folders/companies and would like to be able to copy a sheet from one file to another so that the report does not have to be redeveloped. I know that I can copy all of the individual cells and paste into a new sheet BUT the formating is not copied so I have to reformat the entire worksheet.
