Each custom field must appear as separate column when I generate report

Our use case involves adding multiple custom fields in envelopes to ensure we have a complete record. For example, if I’m signing a contract with Alphabet Inc. and it has been requested by Bruce Wayne, I need both of those information captured as custom fields in my envelope. Now, when I download reports, all custom fields are clubbed into a single column making a mess of the information. I’d like each custom field to be a separate column in the reports.
