Is is possible to add Banagher (Keenaught portion) Civil Parish to the Parish drop-downs?

Hello,

This message is for the the website administration. Is it possible to add Banagher (Keenaght portion) Civil Parish in Derry County to the Parish Dropdowns?  This parish is south of Dungiven in County Derry.  I have an ancestor from Aughlish Townland, and would like to be able to link him to that Parish if possible. Thank you.
