Cosmos Simulation - Random Vibration and Damage

I have a question about results that can be obtained from a cosmos simulation random vibration analysis. I analyzed a small structure with a random vibration profile from 20-2000Hz 18.67 Grms and would like to know if it is possible to export the cumulative damage. From what I see this result is not available in a random vibration loading application. Or is there a better method to obtain an estimated life of the part with cosmos simulation given the PSD.

Generally I work with thermal-fluid systems so most structural work I conduct doesn’t include random vibration, I am trying to learn a little here.

Thanks.
