Can I slice a fluid volume into multiple parts?

I'm currently studying a two-way Fluid-Structure Interaction (FSI) between air and an aircraft wing, and while I managed to do some structured meshing with the wing by slicing its skin into multiple parts and hence reducing the number of elements, I haven't managed to do so with the fluid volume. I'm thinking of doing the same for the fluid volume, but I don't know if that could somehow change the physics of the problem.
If I indeed divide the fluid volume to aim for a more structured meshing how should I define the contact between the fluid volumes? Bonded? Or should I define the fluid domain as a multibody part? I'm not a fan of multibody parts, since they have brought me some trouble in the past. I'm attaching a picture of my fluid domain:
