copy HFSS mesh between projects

I'm trying to model a very high Q (~10^5) resonator and am having trouble finding the S21. I'm able to solve for the resonance frequency using the eigensolver but I can't model the coupling and S21. Since the Q is so high unless I enter the exact adapt frequency the mesh will not be adapted correctly and it will not see the resonance. Is there a way for me to copy the mesh from the eigensolver to use in the driven modal solution? I tried linking the two but since I have to add ports for the driven it gave me an error and said the geometries were different.
