Please provide source codes for templates

When we want to create custom template, only very basic banner is available as starting material and we basically need to build whole banner from scratch.

It would be great if web UI could provide us with the source code of premade templates - so we would configure banner via UI and just make minor changes in the html / css / javascript in the custom template. That would make customization of the banner much more easy a systematic than adding own JS / CSS to the page to modify banner after loading and would greatly improve the desirability of the Cookiebot by our clients (not to mention our ability to deliver such customized banner).

Thank you in advance
