List Combine and List Sort on Attributes v2

Hi All,
There is specific documentation on how to use CMS Combine and CMS Sort with Attributes v1 but none with v2.
Is it still possible?
The bit of JS code provided in the v1 docs and that’s supposed to click the hidden button to trigger the sort seems to be referencing the old function names and doesn’t seem to work anymore.

Thank you!
Vincent
