Log rotation template - manual configuration created from automatic

I have some virtualmin instlations. I want to change “per-domain apache log rotate”. I did it for the existing server, now I want to change it for templates. I can change between “Automatic” and completly made-up configuration. But I don’t want to make up the whole configuration, I want to just take the automatic configuration template and change few numbers. But where can I take the current automatic configuration template?
I would like if there is a “paste” button, which would paste the automatic to the text area and I could edit it after.
