You can certainly do that easily enough, yourself.
You just need to know the .exe name that the Rockmelt browser uses, and the hard disk location of it's profile folder.
Then use both of those at:
Sandbox Settings > Resource Access > File Access > Direct Access
Use the "Add Program" button to enter the .exe name for the browser.
Then use the "Add" button to select the profile folder.
This assumes that the browser is installed outside of any sandbox.
If it's installed inside of a sandbox, then substitute "Full Access" instead of "Direct Access", in the instructions above.
It's possible that the browser might have other .exe names associated with it, as well.
You may have to add those .exe names in the same way as above.
The .exe names should be listed in the Sandboxie Control window, when you run the browser sandboxed.
