Help with topology optimization and error elements missing section

Hi, I am trying to run a topology optimization on an imported mesh (implant over bone with screws)

I normally import all meshes as volume meshes. But when I try to freeze the regions for the optimization, I can not select the surfaces I want to freeze. Is there a way of solving these that is not manually selecting every element that is part of the set?

A solution I was exploring was to also import the object's surface mesh, as it creates the sets for freezing. The problem with this solution is that I then get an error saying that some parts have elements without any section assigned.

Is there an appropriate method to select the areas for the freezing constraint?

Thanks in advance
