RobotStudio event

Weldguide, tracking, step by step instructions?

When programming on my S4C controller using ArcLSto and ArcRepL is fairly straightforward. Now that I'm learning RobotStudio this is no longer the case. I was able to import action instruction for ArcRepL so it's now part of action instruction list. But, how do I store a welding path with tracking then replay it in RS?
