Hi everyone, under the module "fleet" Odoo I want to add a new object "park" in connection one2many with "vehicle" (ie, each vehicle is assigned a park x) and for more precision :

1) add to the menu item "Park" before "Vehicles"
2) a form for inserting objects "park" with two attributes (name_parc and adr_parc)
3) define the relationship one2many between park and vehicle
4) addition of linking field park in the vehicles form

questions:

a) I make this change directly on the "fleet" module or i must create another module with inheritance?
b) if possible a small technical description for this change

thank you in advance the Odoos
