RSG §4.7.6 on adding individual disc catalog numbers other than the main cat. # to submissions
nik says to use Supervised By for production assistant - https://www.discogs.com/forum/thread/204402#2546435

Don't put extra characters into Runout fields to distinguish betwwen etched and stamped portions.
• Parentheses are not a part of the Matrix number.
Don't use small-caps or cursive alphabet Unicode in BaOI fields.
Runout variants must be entered in sets.

It is perfectly acceptable to enter Pressing Plant info in the Free Text Field. Staff opinions from Nik and Diognes:

Diognes explains how to do it right (January, 2018): https://www.discogs.com/forum/thread/368277?page=2#7523520

Diognes endorses single-line Lp runout entries in the Forum discussion starting here and ending here, and also in the discussion beginning here and ending here.
Oh, and Here.

How to deal with Corporate legal ending differences...

On explaining stamped vs. etched portions of runouts in BaOI descriptionfields, Diognes_The_Fox says in this Forum thread:
"If there is a good reason for differentiation, it might be a good place to expand that information out in the release notes rather than trying to come up with some system to force it into the matrix area. I have had some instances where knowing about stamped/etched differences was useful, but those are pretty extreme cases."
