Specialist Durability analysis using a nonlinear solver in Siemens NX

I need your help on the following issue: is it possible to use the non-linear results of strength calculations (for example, SOL402/SOL106/SOL129) to calculate Specialist Durability?

Let me explain in a little more detail. For example, if loads on an object (forces/moments) act at several points, and constraints are not specified, then you can specify the loading history (load values) and the results of a single linear FEM-calculation, when unit forces of 1 H and unit moments of 1 H/m are applied to the required points (so-called Superposition Event in NX).
The linear static solver has an Inertia Relief option, which allows you to obtain a solution for loads of 1 H. Unfortunately, nonlinear solvers do not have this option. Trying to use a nonlinear solver does not lead to anything. Perhaps there are other options?..

Thank you in advance.
