MS Bookings - statutory holidays

Hello, 

I am configuring and testing MS Bookings in my company. I would like to know is here any option to add statutory holidays from my country(Poland)? Or i need to add manually all holidays 

Also, is there any way to exclude some entries in the calendar so that bookings does not consider them as "occupied" places? The point is that in addition to the actual meetings, some people add their notes, "internal affairs", etc., which requires periodic "cleaning up" and careful management of this calendar.
