Reverse references to parent table

[vivian]

Hi all,

I have a table with unique data on each row.

Users are allowed to add multiple comment/ note (with specific topic for selection on the form) related to that parent table.

I would like to create slices & cluster the specific topic in difference views with reverse references to the parent table.

Learnt from this articles
https://help.appsheet.com/en/articles/961426-references-between-tables
that reverse reference in the opposite direction will be added automatically by AppSheet but seem that I can’t see any extra column. Is reverse references the method or will IsAPartOf, etc expression can help?

Thanks in advance!
