Copy rows to new table and associate them to a specific customer

Hi, need help creating the following:

  • I have a table for Customers
  • I have a table called “Tasks”
  • I have a table called “Master Tasks List” which is a list of genetic tasks
  • I want to copy all of the rows on the “Master Tasks List” to the “Tasks” table. I am able to do that thru an action but I need the copied tasks to be associated to a selected customer

I think you should be able to use an expression to make an additional column that associates the newly added row to a particular customer.
