Customize the Naming Series for Item DocType in ERPNext

Hello, i’m new with Frappe and ERPNext. Does anyone know how to customize the Naming Series for Item DocType in ERPNext ?

For example, i want to choose between MCH-.YYYY.-.#### AND HDW-.YYYY.-.#### but if i try to use Customize Form feature, i’m not able to change “Options” on Series field because i think it’s protected. My only solution is to activate developer mode and edit the base DocType but…it’s not what i want to do. Is it possible to add customization for the naming series without changing the ERPNext base configuration ?

Search for Document Naming Settings, in there you will be able to set one or more different formats for a DocType

instead of naming setting use document naming rule…

it will help you automate the process instead of selecting series every single time
