Parry +1 AC Circumstance Bonus

I have a monk with a bo staff. When they use an interact action to use Parry, I do not see a way to toggle the +1 AC Circumstance Bonus. For Raise a Shield, you just click a button in the Armor tab to show the shield is raised and they get the +2 AC Circumstance Bonus but I do not see anything similar for the Bo Staff. I also could not find an appropriate Condition or Combat State to toggle.

I created a Temporary Adjustment that was a Circumstance Bonus to AC but that feels like a hack for a feature we should already have. Is there a "better" or "easier" way to reflect that the character is Parrying until their next turn?

If you click on the Bo Staff, then on the Parry trait, there's a toggle on the weapon trait itself to add the AC bonus. Its not a thing we can add an activation to the weapon itself, due to the potential number of traits/properties it might have that include activations, but I've made a note for us to look into this and see if we can convey it more clearly.

Thank you!
