well it is rather hard to do because Pro\M make it all automaticaly
but You can makes some work around to achieve what You want - take a look on tip below:
Tip:
Wildfire 2.0 has added a new edge distribution
mesh control. However, prior to release 2.0 there were already nice
mesh control options available.
Create and/or pattern datum points on a surface or edge of a model.
These points will increase mesh density by forcing element vertices to
be created at the points.
Surface regions can also be used to assist element formation on
surfaces. Also, to increase mesh density inside a volume, volume
regions should be created. And within Autogem settings, lowering the
max aspect ratio from it's default value of 30 can be helpful.
Mesh control is often required for contact analysis when the contact
area is small compared to the elements in contact. Manually controlling
the mesh wont preclude you from running a multipass analysis, automatic
localized mesh refinement will.

I just have a remark... If your goal is to try to get a more accurate result, this is not the best way.
Compare to ANSYS, wich is a h-method solver, you must increase the number of node to get more accurate result. But, Mechanica is a p-method, so you must set an higher polynomial order to get a more accurate result.
For a h-method solver, the equation between the node is linear or quadratic. But for a p=method, the equation is a polynomial.
