My Appraisal - Highly Inefficient

My appraisal page needs the ability to add columns. So when we are touching base with past appraisals, we can easily identify the property (already added), but add the contact name, contact details, email, appraisal low range, appraisal high range. As such, when we are re-visiting clients we have already appraised, we can have all this stored information on one page versus having to click on the property, click on the contact, make the call and then go back to the original page and start all again.
