JGive Donor Details

We are running Joomla! 2.5.16 and Jomsocial 3.1. Is there any way to remove some "Fields" from the JGive Donor Details? Such as "Last Name", "Phone Number", etc.. This is a Jomsocial community and the users choose not to make all there information public. They say it is a bit tedious filling out all that information each time they make a contribution. All there information resides within there profiles already.

Thank You
