Shared Fields - All Current Fields

I think all fields (when created) should be available in the Shared Fields. This saves time when you are creating forms and you are not duplicating fields across multiple forms. It would make reporting and analytics much easier as you are not looking at multiple different fields and can just say I want (for example) the best contact number and instead of looking up a particular form and then the field it would be available to search on by itself so you can find the information in all forms with that field in it. Otherwise, you then have to do a huge overhaul of forms to find and replace specific fields now that the Shared Field is available. Then if you have the same field,  you should be able to merge those fields together and move the information in one field to another to ensure that there is no duplicating of the same field.
