Can i have an AB test with multiple steps with Split gem?

I have a rails application and i want to use Split for AB testing. Is there a way to keep track of multiple steps with Split? I want to keep track of users who clicked an "add to cart" button and then finalised their purchase. Right now it seems the only way to do this is to make 2 separate tests

• first one starting when the user sees the "add to cart" button and finishes when he/she clicks it
• second one starting after user clicked on the button and finishes when he finalises his/her purchase
