How to Append Rows to a Google Search Table with Additional Queries

When I start with a Google Search to create a new table, how can I add additional rows to the table with more Google queries? Eg, I started with the search "california attorney" and got ~150 results. I set up some additional columns to enrich those rows, de-duped results based on those columns, and removed some low-quality results. Now I want to append to the table with results for the Google queries "san francisco attorney" and "los angeles attorney". I could create new tables for each, but then I'd have to set up the other columns again. If I duplicate this table, it doesn't seem to let me edit the starting Google query.
