I have a custom field that I populate at the Submission stage of a Change, it's called DUE DATE (but it could be any other custom field). What I need is for this CF to be shown, at the form, at any stage of the Change Life Cycle that I choose. 
For example, I want my users to be able to read this data without navigating to the Submission stage. 

I have other fields, for example Scheduled Start / End, that are default at the Planning Stage, and given their importance to the CHANGE, I'd like them to be shown on the forms/screens of all stages.  

As it is right now, If I create a Custom Field and drag it into a form, I can not use it anymore in any other stage or form. 

It occurred to me, maybe it's possible to create a CF and "call" the data directly from the database using its field key... I don't know, maybe??
