Bulk refresh of columns?

[Mark Andrew Miller]

I am building most of my URIs with UUIDs. The UUIDs are created in a new PyTransform column
import uuid
return uuid.uuid4().urn[9:]

And then pasting the UUID into other URI columns with another PyTransform
return 'heightDatum/' + getValue("row_uuid")

When instantiating a new source data table, I I refresh the UUID column with the circular arrow icon, but then I have to click the refresh icon for all (20+) columns that use the UUID. Is there a way to do that as a bulk operation?

You can click "Publish Model" at any point and that will re-run the model if there are any edits to existing transforms, thereby refreshing all the columns.
