Differents comments in a list

[Himaladin]

Add comments to a detail screen

If another user, such as an admin is supposed to be able to view these comments, then user specific columns is not the right choice here. So this is going to be a one to many relationship between instruction and comments. You will need a separate table for this, a relation or query between the two tables, and then each comment will be written to separate rows. Do not use user specific columns in that new table.
