Is there way to have a Sell on the books and also a stop-loss for it on GDAX?

Hi, I've got a sell order high up on the books. However I am concerned the trend may go downwards instead of continuing up.
I trade on Pro.Coinbase currently.

Can I have a stop-loss for my sell order on the books? I would've thought this is essential, otherwise you need to sit in front of the computer with a stop-loss on your coins, waiting for your moment to take your desired price from the books - instead of putting an order on the books and waiting for it to be filled...
