Split a surface?

Hi again.

Is it possible to split a surface into 2 surfaces simlar to the "split" function that only works on solids? I'm not intersted to just make a split line because then the surface is still only one body. I could of course make a copy of the surface and then use "trim surface" a couple of times, but it doesn't feel like the easiest way to go.

Thank you in advance for your answers.
