Is there a way to create expectation suite from code on the fly?  
I know how to create checkpoint,  
and I know there is “interactive validator” approach like this:

validator.expect\_column\_values\_to\_not\_be\_null(column=“passenger\_count”)

but I do NOT need to RUN the expectation with validator immediately,  
I need to **reconstruct expectation suite with all expectations** I need and then run a Checkpoint ONLY ONCE
