Zach Let me check if I understand you correctly... you already use a specific account for something you save for?
What you can do in that case... is still create a new Savings Goal and setup Auto Save... you then select the accounts that you want to use in the Auto Save feature. When you use these accounts, you will still automatically save money. And once in a while you can transfer all you have saved up so far too that account you already have now. This can be done with a few clicks.
This way you can use the system you already have setup, but still use the cool Auto Save feature.
