Lumira save story; update dataset

Hi,

We are currently developing a story in Lumira and it has 5 pages. Our challenge is that our data source (an AWS Redshift cluster) is updated once in awhile with schema changes, modified data types, etc...

Everytime we need to create a new dataset and recreate all visuals. I hope there is a better workflow and that someone can show us a more efficient approach.

Can existing stories be saved and the underlying data set be changed?

We understand that it may require some rework for new/different columns but we don't want to start all over for a minor schema change.

Thanks in advance for the suggestions with a better, more productive workflow.
