How to probe specific rows of a table with ChatGPT actions?

I have a table X that contains rows from multiple users. Each row is user-assigned via a column named UserID where I store the rowID of the user from the Users table.
How do I set the Row Specifier in the “Answer a question about a table” action for ChatGPT to only analyze rows assigned to a specific user?

I think the row specifier is more like a “helper” for Glide to find the row, not a “filter” to only include specific rows.

That sucks. I was really hoping it could be used as a filter for the table analysis.

You can use a relation + joined list column to get the info from specific rows, and then use a normal “Generate text” action with info coming from your joined list integrated into the prompt.
