Custom Field label vs. name

Allow a custom field label customizable by custom form. For example, currently in our Education instance there are four custom fields about campus - Campus, Desired campus, MCASOM Campus Support, Select Campus. I'm creating a new form where we like the name to be "Student Home Campus" The Select Campus field has the selection I need, but if I change the label to meet the needs of the form it will change it for any other forms it's on. We are basically re-inventing the wheel each time when we could reduce the number of fields needed.
