Help with ChatSetAttr

I am using !setattr --sel --other_resource|[[@{selected|other_resource}-1]] to reduce the uses but cant find a way to enter it into a entry in the features and traits section of the 5e OLG character sheet.

Could you give some details on what you actually want to accomplish? I cannot parse "cant find a way to enter it into a entry in the features and traits section of the 5e OLG character sheet". What exactly do you want to enter into that section?

on the OLG character sheets you have a section to enter your characters features and traits that when clicked enter what is typed in it into the chat.  I want to af the text command !setattr --sel --other_resource|[[@{selected|other_resource}-1]] to lower the uses of the feature i am using for example barbarians rage while also entering the description into the chat. I can manage this as a self built macro but wanted to find a way to add it into already existing sheet sections.

I would have thought this would be built into the companion script, but I don't see it. Just ammo and death saves?
