How to change dropdown values for Customer Status

I want to add more selections to the Customer Status dropdown list in the Customer screen.  (see screenshot below), which I am certain I can do with customization and PXString list. 

The question I have is this : Will I cause any issues by adding more selections to this dropdown list?

NOTE : The selections I want to add are literally just various versions of Credit Hold.  Like Credit Hold - Cash only, kind of option.
