Restrict type of supplier entry by responsibility

 We have a requirement to allow users of a responsibility to only enter certain types of suppliers. E.g. responsibility A may only create suppliers of type X,Y,Z while responsibility B may only create suppliers of type D,E,F. (based on vendor type lookup). If anyone knows a way to do this in 11.5.10 e.g. via personalizing the form, I would appreciate hearing from you!

Thanks in advance.
