Is a own mesh possible for a branch-groub at the treecreator?

Hey guys,

I actually played around with the Unity - TreeCreator and I'am not satisfied and happy with the results. There are a lot of unnatural things that have to been fixed by hand. I actually want to use my own mesh for the trunk and for the brenches, so are there some possibilities to use my own mesh as a branch-group in the tree-creator instead of the mesh that the tree-creator had created ?

Also I want to create my own mesh for the trunk and the branches, but the leaves are meant to be created with the TreeCreator .. any possibilities ?

I created my trees completely in my 3D-application before and didn't create something with the tree-creator before in fact, so I don't know really about the possibilities and the documentation havn't a answer as well ...
