Is there way to repair mossed tinkers tool, without having it on the hotbar? (Direwolf20 pack)

i just wonder if such thing is possible.(playing direwolf20 pack, Tinkers Construct hammer)

i found out there is bug for flux upgrade, it recharging on hotbar, so i had no choice but to use moss upgrade or use ingot to repair my TC hammer.

the problem is that my hotbar is already over crowded and i do not have extra space to carry my mossed hammer just for repair.

i do not really want to waste tons of ingot to repair the tool, so i want to know if there is way to let the moss auto...
