How can I apply Cyclic loading in ANSYS Mechanical APDL as a second Load step after a Static 1st Load step?

I am simulating a masonry wall under in-plane cyclic loading. Before the cyclic load is applied, it must be loaded with gravity direction surcharge load (or pre-compression). However, whenever I...
