Your text is not very clear, as was on this other thread. Please describe what you mean in clear sentences and not in abbreviated colloquial form.
If you mean that after you've changed settings, you will need to re-import the respective skeleton asset's parent folder: yes, you need to. You might also need to delete the generated assets beforehand, as some are kept so that you don't loose your custom settings on every re-import.
