Upon dedication to Zeus, you're blessed with a Guardian Daimon.
You don't choose who this is, but whomever it is, they are the best fit for you on your Path to the Godhead.
In time, you'll discover the identity of your GD.
The Guardian is assigned, however, this should not stop you from asking other Gods for help if you desire to do so.
