Ability to force a variable to lower case

I would like there to be a way to force variables to lower case from the admin console. There are a couple ways to make it happen. When setting up a prop or an eVar there could be the option to "force all to lowercase" so I wouldn't see ford, Ford and FORD in the report. This could also be handled by a change to the processing rules as well. There could be the "force to lowercase", "force to uppercase", or "force to propercase" options for any variable. I prefer the processing rules method, but either will work in the long run. Sure I can make this happen myself with some JavaScript in the s_code file, but it would be nice to do in from admin.
