Add options to clone/copy custom working time :)

Add options to clone/copy custom working time, this options will save a lot of time to making custom working time.
For example:
if i have in first and tree mount weeks working time from 09:00 till 13:00,
and in second and for mount weeks my work time start from 13:00 till 18:00 and this repeat all year.
if i have that options a will change only period in calendar , this options will save a lot of time to making custom working time.
