I might not be clear enough!! I'm sorry, I'll try to be more concise!
This is what I want to do: I duplicate a tree (let say the Plant Basic Evergreen tree 03) and then I give the latin names etc that I want... When I'm done changing all the settings and press OK, and it usually works, the plant with the right plant symbol is ready to be placed on my design.
But my problem is that right now, when I press OK, it automatically changes the Plant Basic Evergreen tree 03 to a Grass 02 symbol... (I don't know why this one!!)...
So I don't want to change a symbol as much as get the right symbol for the plant I chose!
