Manuals/Tomes and inherent bonuses to ability scores

[Bellona]

I'm trying to edit some character portfolios to show that the characters have read a magical Manual (Gainful Exercise, Quickness of Action, Bodily Health) or Tome (Clear Thought, Understanding, Leadership and Influence). The magical items in question give an inherent bonus to one particular ability score.

How do I do this, short of forcing through the change under the Personal/Permanent Adjustment tab? If I do it that way, there isn't even a drop-down menu asking me what type of bonus it is (beyond which ability score is affected).

Ideally there should be something added to the magical item itself, to show that the character has used it.
