Device Configuration Report ?

On just about everything there is a comment field, is there a way to display those in a report, ie: using the below

select from_dtime(dtime) as time, devid, `user` as user, action, cfgobj, msg from $log-event where $filter and type='event' and subtype='system' and cfgattr is not null and cfgobj is not null order by time desc

is there a way to include the comment field? If so what would that variable be? We would like to create a change log, that shows really the following:

date | user | action | msg | comment
