Why do you have to input/map 'collName' for every pointer in a service?

[Jack Bua]

In every service, like the one pictured below, you have to map a collection name to the collName field.

1. Why is this?

Do you want the collection name to be entered automatically? In general, the Pointer can reference any collection, not just Users.

My second question didn't get included in this post, my apologies.

my understanding is that a pointer value in a collection can only point to one pre-specified collection, but yet the service request for that collection is open-ended.

Question 2: Does that mean that there is a way to make a pointer point to more than one collection?

[maxkatz]

You can point the pointer to any collection column.

I did not know that. Thank you.
