Place a sell order for the amount of coins you WILL have when the deposit is finished. It will show only as the amount you have currently but when the BTC deposit clears, the whole order will show. I did this last night and it worked.
This is the only way I know to do it. If you want to always do it, set your order for 21,000,000 BTC or some other large number. It will always fill what it can.
