Is it possible to split or section the surface component into several parts?

[[To...]]

I would like to split my surface component into several parts so that it is possible to evaluate different parts of my sample without having to create a surface component in each part, as shown in the attached image. It would be possible? If yes, through which steps?

Thank you very much.
