@roofboard Please open a new topic instead of necro bumping old topics with semi related answers.
Now to your question.
Right now there is no official way of doing this.
And also I would not recommend of doing this.
Do not expect support for the following.
But against my advice, and now this is theoretical, I have not tried it but in theory it should work.
Yes you could do that even, semi permanent.
You could edit the image of the app on the server and commit the changes.
BUT WHY?
If you know there is a problem AND you know how to fix it, why don't you commit your change?
Here is the repo: https://git.cloudron.io/cloudron/n8n-app
Please, if you know of a problem submit a PR.
