Add bulk data rows

Hi everyone,

I have a Teams table and a Tournaments table.

I also have a Teams in Tournament table (Team ID + Tournament ID).

When I create a new Tournament, I want to automatically add multiple rows in Teams in Tournament. One row for each existing Team, all linked to the same Tournament ID.

I’m on the Maker plan. What’s the best and least costly way to do this? I wish to stick with Glide Tables but open to ways to do this on Big Tables as well.
