How to generate authomatically the title of a content?

I am writing to ask if someone knows how to generate automatically the title of of a node.
For instance i would like that the content A is automatically identified as Content A_1, Content A_2 …

Hello Joao,

I did a small search but I didnt find an out-of-the-box solution for that. In general the title cannot be easily modified. Even to disable it, you would have to create a module to override it.

In general I think a good shot would be to create a module that uses hook_form_FORM_ID_alter and add it as placeholder in the form.
