I don't know- i guess it's because i think each paycheck coming in must be RLMed so that specific amount is LM. I think of it as directional and specific- not just 'touching' the account. So i understand only the $ moved are LM; not any remaining $ in the original acct.
Are you saying that the total $ in the on-line acct is now LM because a RLM transaction was done against it? That would simplify matters.
