Silly question... how can I delete a role based Dropdown?
I created one for the wrong role and want to get rid of it but I am not seeing a delete option in Studio, nor can I change the role to the right one... 
We are on-site so manual back-end solutions are acceptable too, but I don't see a difference in
custom/Extension/application/Ext/Language
for Role dependent drop-downs and am a bit too lazy today to reverse engineer where these role-dependent options are stored 
Thanks,
Francesca
