For a one-off case you can probably hardcode the components to check the value of the "serial number" for the next/previous rows, and do different trickery in the saveInto parameter to handle data clearing, etc. But if you want it to be truly dynamic, you will need to build in some sort of relational hierarchy between your questions, on the database side, where for any given question you'd be able to check in that row's logic whether it should behave in any special way depending on the relationship between questions. Be advised though, this will get pretty complicated.
