Good morning,

I need your help because I'm tearing my hair out :) !

I have 2 questions:

The first question is, do I have a many2many field in etiquette mode. With labels like ISS or 2ER etc... And I want to do an automation. 

For example: If I receive a mail with the subject ISS then insert in the field many2many 

ISS 

My second question is how to delete all the fields we created before and that remain in the list on the left side of odoo.
