Sort Import actions by process assigned too

Import actions keep building up in the entire project. The import actions are often a mess  and difficult to find/search in the huge list.

Is it possible to sort the Actions by process they are assigned to ?

For example:- In sprint 1 , we created approx. 150 actions and assigned them to some 10 processes.

                       In Sprint 2, we create 50 new actions and would like each of these actions arranged with respect to the process they are                                 assigned  to. 

 So, here getting a sort option by process, auto clusters the actions w.r.t their processes rather searching and and clustering manually.

Thanks,
