Hey Marcel!
Thanks for reaching out, and for the link to the existing version of the “scheme” you are trying to recreate here.
Our plugins unfortunately do not offer a “scheme” layout or feature that looks like the one you are trying to build 🙁
I’m sorry about this!
It would indeed require a large amount of custom coding.
I don’t know of any alternative plugins to suggest that do have these features, but if hiring someone is something you’re interested in, we have a list of customizers here that might be helpful → http://m.tri.be/18k1
We have no affiliation with those folks, they’re just some well-respected names in the community that we’ve compiled.
Cheers!
George
