Add additional rows to table based on connector call

Content

At the moment I have a button with a "on click" event which invokes rest api, stores the response and then populates the table using tablecontrol->SELF option in action. This works well and table is populated based on the data returned by the REST API.

 

Now when user clicks the button again (based on different search parameters), I want the data returned from this second query to populate the table but append instead of overriding the data populated from first response.

 

Is this possible?  If yes, how do I do it? I have explored all the options available on table control (like Self, Last, Selected etc) but I can't get it to work.
