Is there a way to make my bot go Storage->Sell->Buy sequence

Is there a way to make my bot go Storage->Sell->Buy sequence? I notice that when goes back to town when it runs out of potion, it goes directly to NPC tool dealer to buy the potions instead of reducing the load of its weight by storing (e.g item 0 1 0) in kafra and sell (e.g item 0 0 1). So when may bot goes back, with 85+% full of weight, it can't buy 250 Yellow Potion (as set in buyAuto) since it will exceed its weight limit and the bot is stuck in front of the tool dealer repeating the sequence of buying/fail to buy again and again.
