The One Ring problems with the character sheet for the redoubtable cultural blessing

When using The One Ring character sheet for roll20 I noticed that the fatigue score is locked since it's automatically calculated. The problem with this is I have two players (I'm the LM for the game) that have the redoubtable cultural blessing. With the blessing they are able to take the total of their favored body score off their fatigue score when making their character. I can't find a way to implement that in the character sheet.

Maybe you can add a line in your Gear with a negative encumbrance. Something like : Redoubtable cultural blessing      encumbrance = - Favored Body value

I kind of solved it by taking off the encumbrance that the players get from some of the weapons or armor. So the numbers for the items aren't right but it balanced out the fatigue score to what the players should have.

I guess a field for a "misc. mod" for Endurance could be added there. Is the fatigue score changed by other things after character creation than the base stats and how much they carry?

The fatigue score can change throughout the game due to failing travel rolls, but there's a place for temporary fatigue and permanent fatigue. It's the permanent I'm trying to change. Of course if the players were to get different gear later on then the fatigue would change because the items would change. To be honest I'm pretty new to using Roll20 and the character sheet isn't one I made myself but one that I found through the community.
