As an Administrator, you can add a timeframe restriction that will prevent Officers from creating Events on short notice. For example, if your timeframe restriction has been set to two days, Officers will not be able to create Events that will take place earlier than two days from the date they are submitting the Event.
Click the Admin button on the top bar

Click the Settings menu option in the sidebar, then select General Settings in the dropdown menu

Select the Events tab in the top of the main content area

Scroll down to Restriction timeframe create event and enter your desired timeframe in number of days, then click Save
