Help with computing stresses in random analysis for a large model. Can I do a restart from a modal analysis to speed up the solution?

I have a large model that I want to compute RMS stresses for. The model includes both plate and solid elements.

Previously, I used NX SimCenter and generated stresses for random analysis based on a modal solution. I generated modal stresses/displacements prior to importing the solution into SimCenter. In MSC, I wasnt sure if the database needed specific entries to drive the random stress case.
