Answer:

Yep, sure is... By, clicking the 'undo' button associated with your content import, it will remove all content and other meta data associated with that import. Here's a quick walkthrough:

1. Click your name in the upper right hand of the platform and select Calendar Admin.
2. From the Calendar Admin, click the Content Imports tab on the far right.
3. From the calendar selector, select the calendar to which you imported the content.
4. Browse through the list of past imports and click the "Undo" link associated with the import you want to remove.

Once the undo process has been completed, you will see a 'success' message where the 'undo' link used to reside.
