Add Columns to BigQuery

I am aware we can append context json to BQ table, but is it possible to add column to the BQ data set,
For Example:
I am want “x” parameter value from js tracker to be displayed in “X” column of BQ table.

Thanks in advance.

Can you give an example you have in mind of what value this is?

If you wanted to do this generally we’d recommend surfacing this in a data model that derived from your events table (that references a unstruct_event / context) rather than as a top level column.
