Copy custom GL reports from one company to another

A customer will have several companies that need customized financial reports which have been developed and tested in one company.  The same Chart of Accounts and Account Groups exist in each company so we don't anticipate a problem sharing them, but I can't figure out how can I copy from one to another.  This is using the Sage 100 financial reporting (not Sage Intelligence), Sage 100 v 2018, standard edition.

Thanks.
