Please add option to add more branches or second lvl

Hello i really like your software but i have some problems for making good looking norway spruce tree. Can you add option to add more branches? Can I add my own mesh for leaves? How to do this?

Finally i make my tree. Effect is not bad but can be better. One option is missing. For Example leaves on upper branches are to much i think. It's nice if we can modify how much branches is depending on tree high.
