Hello @micha009,
Currently, there is no such feature in the theme and as much as we would love to help you with this we are unable to do so as it requires higher code customization.
So our suggestion to you is hire a professional developer so that your code won’t be affected and you would get what you want.
To hire a developer please refer to below given link:

Thank you.
