Possible to add Custom Fields?

Is it possible to add custom fields to the Jobs and Experts plugin?

For instance, my board is for both volunteers and paid workers - I would like to add a volunteers question., health status (I serve a chronic illness community), hours available, more contact information, etc.

I would also to be able to add a place for links - I would like put a link from a job - which we are calling Projects - to a project management tool we are installing on Wordpress...
