Currently we do not have a direct means to add a blank space to a report. We understand the need for this sort of feature and have created an Idea on our Community page to this effect. Please navigate to https://community.blackbaud.com and log in or create an account. Once logged in, you may navigate to the Idea page below in order to comment and vote on the Idea:

Remember, the more votes an IDEA receives, the more traction it will build with our Product Managers, so please encourage your colleagues to vote on the Idea as well!
