Hi, 

Is there a way to have Zapier update the custom fields of two or more Click up tasks?

I have a folder with two lists. I have a task with a custom quantity field on one list and I want that quantity to be added to the custom quantity filed of another task located at the second list. The custom fields settings are the same for both lists. I would like the above to be an ongoing action as the first list’s tasks needs to update the second list’s tasks.
