Custom Field Profile

Hi guys,

I would like a feedback by some of you. There is an option in custom field profile configuration where we have: Allow Profile Edits: *.

There are some options to be selected. But I need to allow field to edit “ONLY IF ITS AN EMPTY FIELD”. Can some one give me an idea about how to do it? Is it possible to suggest it as a new feature in s2member plugin?
