Path mapper and list operations

Hi all again,

is there a way to make list operations directly in the pathmapper.?
At the moment i change a list with a tree and put it back after some list operations.

I am also curious if a tree (a column of branches in the param viewer ? ) could be seperated.?

Some help would be really appreciated

Depends on what you mean by separated. The path mapper can do some operations (flatten, partial flatten, graft, reverse, renumbering of paths, simplification of paths, matrix flipping, …) but not all.
