Is there any way to unify the Source pick lists?

Is there any way to unify the Source pick lists?

I'm very happy with most of the features in Zoho CRM, but I would like to have a global pick list for "Source," whether it is "Lead Source" or "Contact Source" or "Account Source," so that I don't have to modify the pick list in multiple locations every time I add a new source. I want to be able to track the same sources in all of the modules.

Any way to do this? I couldn't find it in the documentation. Thanks!
