Not as of yet. There is a suggestion for this in the New Feature Tracker:
https://www.tcdb.com/FeatureTracker.cfm?MODE=VIEW&ID=229
If you rank this a "1", it means it's your highest priority item.
I recommend everyone go there and vote on the items that mean the most to you. It helps Admin know what's important to the membership, and helps prioritize updates.
