Today the defaults always persist for new symbols - i.e. if you want your symbols to be Static you need to select this option manually from a dropdown every single time you create a symbol. If the Symbol Options dialog simply remembered the previous choice it would be super helpful.

Today you can drag a linked image into the symbols palette, name your symbol, configure your symbol choices, then click OK - only then is an error shown that 'a symbol definition cannot contain a linked image'. It would be way more helpful to provide this feedback on the drag into the palette, before users name and configure their symbols.
