I have set my export preferences in the "presets list"
Is there a way to make my saved setting the default when I export to jpeg?
Short answer No!
But you can save it as a preset!
Just set up your export dialogue as you want it then click the little arrow to the side and give it a name.
I put a 1 in front of the name so it is at the top of the list.
Thats exactly how I do it ATM.
I was hoping I could default it from custom to my saved preset.
Yes it's crazy that it does not remember your last setting.
my advice is to use a macro such as http://macromonster.com/index.php?mod=descr&id_desc=23
