Yes that is exactly the question.

Can't we have a more generalised command that cover all the above scenarios?
i.e specify which column to aggregate with and which to comma separate.

Am I being clear or is this too complex?

mkcover - HylaFAX continuation cover page generation command SYNOPSIS
/var/spool/fax/bin/mkcover qfile template result DESCRIPTION
bin/mkcover is the command invoked by the facsimile server when a continuation cover page is required for an outbound job that is about to be retried. It generates a single POSTSCRIPT(R) page that is imaged according to the remote capabilities and transmitted as the cover page. The arguments are: qfile the job description file for the outbound job. template the cover page template file, as used by the faxcover(1) program. result the filename where the resultant POSTSCRIPT document should be written. The default mkcover command is a shell script that uses awk(1) to parse the job description file and generate the cover page document. The template file may be optionally compressed with compress(1), pack(1), or gzip(1); the filename suffix is used to decide whether or not the template file contains compressed data. SEE ALSO
