Mycred Gravityforms Gravity Forms Addons

Hello!
Many thanks for mycred, is for me the best in class !
I’m building a site points where my client needs to add custom points directly in the edit page of messages , it works like this :
1 – The subscriber prenche a form requesting points ;
2 – The admin checks the message and if it is ok it adds points to the subscriber ;
To create the forms I’m using Gravity Forms and edit posts Gravity Forms Directory.

What I need is a text field on the edit page of only visible to admin ( Points ) that serves as the text field that mycred adds to the edit user profile page , the admin messages fills the number of points be added and save the message points are recorded in the subscriber profile that filled out the form .

I searched for quite some solution already exists but not found , it will be that I am the first to try this ?

Any help or hint is welcome!
