CRUD functionality for laravel and fulcallendar

Currently there is add new entry functionality
Update functionality should work in a following way.
For each property there is calendar with dates.
Client will probably select whole summer as as one period (1.06-30.9) , set price (100) and minimum stay (7) for one property.
during this period for example 25.07.-30.07. he wants to change price to 90 and min stay to 2
he should do this just by selecting range 25.07.-30.07. and entering new values while rest of period (1.06-25.07 and 30.07-30.9) should keep values 100 for price and 7 for min stay.
