Is it possible to make strafing animations in Unreal editor?

I found an animation pack in the Unreal marketplace that I am interested in getting. It is rigged to the Epic Skeleton. It has walk and run animation but no strafing (walking side-to-side or diagonal). I was wondering if its possible to make those animations from the walk or run animation within the Animation Editor in UE4? How do I make the custom strafing animations?

I never used blender or made animations before so that’s why I wanted to do it through UE4’s editor with this animation pack.

I believe this will help with what you want to achieve
