Most transcriptions that only belong to one fact for one person (or just a few persons), I put in the FACT NOTE. The note you described is the Source Note, which as you've seen is not printable in any report. The Fact Note, on the other hand, is printable in the all-important Genealogy (Register) Reports (either Ahnentafel or Descendant), by checking the box to include Fact Notes.
Examples of that include birth and death certificate information (from FTM databases, I copy and paste the info that FTM has transcribed in the "printer-friendly" option.)
In other cases, I put the transcribed info in a Notepad file which I attach to the source as Source Media. I use this, for example, where an obituary names a lot of people. By including the transcription as an attached media item, it will be attached to whoever is mentioned in the obituary.
Sometimes, I'll do both. The Fact Note that I have created called "Obituary" of the deceased person so that it will print in a Genealogy Report under that person - but also in the source media so that I can see it immediately from within my FTM when I am at another person's Person Tab - so I don't have to navigate back to the deceased person's Person Tab. Source media never prints in a report.
