SAME AS not only for reference field (Dataset option)

How about having an SAME as not only for reference field?
How about on ID field?

So that we can filter the comments based on ID on not doing a very complicated code with a basic function on a website.

What you mean is that you want to use the Same As for any kind of field between two Data Collections? When do you need this feature?

Hi there Mr. Kviby,
Thank you for the reply.

It’s like that but i understand its not yet possible.
I am thinking to make a comment box and filter comments based on the ID. Since comments should be in other database, i think same as option will do? I cant see a good tutorial on how to make a comment box on a dynamic pages. Also i like to use the star rating user input of wix.
