Feature to show preference for longer sits in a specified country over winter

I would like a feature that categorises sitters into their sitting location preferences.
I know that I can apply for any sits on the site and am often asked as I am already in Europe (Germany). However, a check box where I could indicate that my preference would be longer sits in France and Spain over the winter months or any other country that takes our whim would make us and other similar minded sitters availablity more visible and probably save local HO messaging people whose direction of choice has no bearing on the sit offered.
