I have worked with auto arms for quite a while, and the most frustrating thing about them is there seems to be no priority as to which auto arm picks up an item first. For example, if I had two auto arms, one behind the other, and both input's are on a single storage, it is completely random as to which auto arm picks up the item. Even limiting power input does not seem to help. My suggestion is to have the ability to pick a single slot within the input range and output range to pull from and push to. For example, you could have four auto arms, all with their input ranges on a storage with lets say four slots. Auto arm "A" could be set to ONLY pull from slot "A" in the storage, whilst auto arm "B" could be set to ONLY pull from slot "B" in the storage, etc. If not this, then at least having some predictable priority as to which auto arm in a set would pull first, i.e. the closest auto arm to the item, or something similar.
