Adjustment Tab - Add Concentration Condition

[AirKevin]

I am trying to figure out how to add a "Concentration" condition in the Adjustment Tab and/or on the Tactical Console where you mark conditions or apply healing/ damage, i.e. "Prone".

I want to be able to mark a checkbox when a spellcaster is concentrating on a spell so I don't have to try and remember, duration would obviously help with how many rounds it's been as well...

I'm pretty new to the editor and can't seem to figure it out on my own unfortunately. Thanks for any advice you folks might have!
