Actually, there isn't any "Forest Lister" or similar tool available and I'm afraid in this case (reassigning a preset) it's not so simple as for example multiple surface reassignment
, which can be easily performed with help of Maxscript.
Well, any similar feature (as option to copy settings between Forest objects) isn't implemented, because in each case the parameters to copy or keep would be different. And obviously, copying all settings has the same effect as cloning the Forest object.
Anyway, we'll see what can done in future releases regarding that topic.
