Earn leave from calender year, use it from May to april following year

Dear Appogee 

First of all thank you a very nice app. 

In Denmark "You earn holiday in the calendar year - ie January to December. The vacation you earn, you can use in the following year, which is from May to April. For example if you have been employed throughout 2015, you are entitled to 5 weeks of vacation during the period from 1 May 2016 to 30 April 2017."

In settings you only have "Leave Start Month" (picture attached file). 

Thank you in advance. 

Best Regards
