Unfortunately, that's not possible right now. Sorry.
But! You can mark this question "answered" and then add the functionality you'd like to the IdeaExchange (https://success.salesforce.com/ideaSearch). <---- Click that link (https://success.salesforce.com/ideaSearch), click the blue "post an idea" button on the right, and then type what you'd like to see in Salesforce. People will vote on it and Salesforce can add it to a future release if it gets enough support.
Also, after you've done that if you come back here and post a link to your idea post, people searching for this and seeing it answered will be able to pop over and vote for your idea!
Hope that helps!
