Here's what one of the sheet authors, Roll20 Dev Steve K, said regarding this matter: I didn't go that granular with my first pass of the inventory system. It
might come with another pass. For now you could create a new character
that's the beast and use their inventory. Or, if fine tracking of
inventory and weight isn't a big deal when it comes to beasts of burden
just track it on the Bio tab or switch to simple inventory from the
settings tab.
