How to disable automatic activation of crop ratio?

I work a lot with cropping during my workflow. Older versions of this software has no locked ratio per default, the 5.0 always selects the Lock Ratio check-box on every image. This is rather annoying to deselect it first and then do my job. Is there a way to make it unchecked by default or do I have to patch sources and compile it on my own (<- would be a sad option)?

As with every setting in rt you can make your own profile (with in this case lock ratio disabled) and use this profile as your default profile
