# Is there a more efficient way to edit actions alread used in NLA?

When not happy with the results in an animation the action can be edited again (Tab in NLA-editor). After that the action is displayed with a snowflake indicating that it needs to be freezed again.

After editing

After adding the updated action (Shift-A Add Action Strip) shown as Walk.001

Do I really need to replace all occurences of the edited action in the NLA-editor or is there a another way to apply changes (in place) ?
