How to export branches/trunks and leaves as one mesh?

I know this was possible in an older version of Tree It. Is it not possible in the latest version? I tried downloading some older versions but none of them had the option in the export tab.

Does anyone know if it is possible?

Thanks for your help.

can you explain what do you mean with "branches/trunks and leaves as one mesh"? please

When exported as an fbx or obj and loaded into blender or ue4, the tree imports as two separate objects, one for the leaves and one for the trunk.

EDIT: Nevermind, I found an option on import to combine the meshes. My bad!
