I have a need for some special content, basically an article post with tags and then integration with a special commenting application.  I am planning on using jomsocial, and as part of the jomsocial profile having a special flag.  Users will be able to select up to four different flags associated with their account.  When a user submits a K2 article, I'll need to somehow pull the information from the jomsocial profile and then ad a dropdown that is limited to just the flags associated with the member profile.Questions:1) Can I add a custom field that will auto-fill programatically based on jomsocial database values?2) Where would I go about doing this?  Is this doable through template overrides?  Or would it require development of a K2 addon?  Or none of the above?Next, I'll need to have a somewhat customized comments module.  Question:3) Would the easiest way to do this be to add JomComments and hack it?
