Thank you.
In my case (with the way JsonManager looping works), there is a sub-event under the loop to test for conditions within the loop, and a parent event, that for the loop itself.
Placing an empty event underneave the jsonManager loop doesn't seem possible, but i can place it as a "sibling" underleave the top parent.
Will try this out once google sheets api comes online again -- for some reason, the google sheets api suddently stops responding to ajax calls, and after some wait (30 min? an hour?) it suddenly works again.
anyway, thanks, will give it a try
