Incremental loading / Structural scenario app

Good morning,

may I ask if there is a method to apply incremental loading in the structural scenario app? I need force 1 to increase in each frame while force 2 is the same in all frames.

I tried changing the setting of the static step to increase the load in 10 frames (like the image below). however, that would affect both forces 1 and 2.

Thank you for your help in advance
