Step 3: Type of Room Block
Note: when you create these blocks, you also have the option to select all rooms and apply the block for all of them.
When you do this, you will have to click "treat these together as one event", this way, later you will also be able to remove the block all together in the future.
Remove the block
You can easily remove the room block by clicking on the block and select the option to "clear dates"(1) - this will remove the block only for that particular room;
If you create a block for more than one room together, you also have the option to "Cancel Group Dates" (2), this will remove the block of all blocked rooms.
