Would your manual not tell you if that could be done? "I feel your pain"..haha..cause my emb machine drove me nuts with the message that bobbin was low..yet when I ck'd it would be half full. I finally adjusted the bobbin case/laser and now it is only a couple of yards from being empty when the message comes up. Plus, I've discovered the prewound bobbins have LOTS more thread than our machines will wind!
