Candidate availability

Hi, The candidates I have in Zoho are all short term contractors - usually spending 3, 6 or 12 months on client sites. When I call them I always record their availability ie when their current contract finishes and put it in an excel spreadsheet. It'd be great to have a feature on the Zoho search results which shows: 1) When the candidate is next available (obviously having previously been inputted by me), and 2) If I could select to order the results chronologically as per candidate availability. Is this a feature that could be considered? Thanks James
