Shaunzam,
The thing is that you can create point loads and restraints however they have to placed on a vertex of the model. What it sounds like to me is that you want to load a center of a hole and the problem with that is that there is no mesh at the center of the hole.
What you could try is creating a point in the desired place (center of the hole) and then selecting the inside face of the hole and applying a remote load using that point at focal point of the load.
Hope that gives you some ideas.
Regards,
Jon
