Run multiple analysis using single gravity loading step (ABAQUS)

I am analysing Masonry infill frame using 3 loading steps in ABAQUS. The first step is Gravity load followed by In-plane loading and then by out-of-plane loading. I have to run multiple analyses in which only the time period of step -2 (in-plane loading step) changes. Every time I run the analysis the gravity step also has to be carried out. But since my model is same but only the time period of loading changes in intermediate step changes, I would like to carry out the gravity loading step once and then perform the other analyses with different time period of second step from this single result. It can save the computation time drastically. Is there any way to do it?
