The only way to implement the above example through the current interface is to add 21 attributes to Survey #2 (Attribute_20 through Attribute_31), then delete Attribute_20 through Attribute_30 one-by-one.

Imagine a scenario where a larger sequence of surveys than just two are coordinated together. Participant tables, conditions, statements, and equations become simpler to manage across surveys where common attribute numbering is shared across surveys. This can be accomplished now, though can take some time to setup when managed through the interface when many attributes are involved.
