Optimization Module : Using design variable of previous iteration

Hello, I am using Optimization Module and having some difficulties.

I want to use the values of design variable of previous iterations (n-1, and n-2).

In other words, can I store the values of design variable of previous iterations (n-1, and n-2)?

I know that the Optimization solver internally has to store and use it to calculate the gradient for the update of values.

But it seems to me that I can't access that information.

Is there a way to do that?

I would really appreciate your help.

Thank you.
