Hi,

You can create a menu under the inventory control module for this you have to set the parent of new menu as inventory control. Then define the action for the menu also its corresponding views also define the new fields in py file.
id of the inventory control menu "stock.menu_stock_inventory_control". you can also refer the below code,

<record id="action_rental_report" model="ir.actions.act_window">
    <field name="name">Rental Report</field>
    <field name="res_model">rental.report.wizard</field>
    <field name="view_type">form</field>
    <field name="view_mode">tree,form</field>
    <field name="view_id" ref="view_rental_report"/>
    <field name="target">new</field>
</record>

<menuitem id="rental_report_menu" name="Rental Report" parent="sales_team.menu_sale_report" action="action_rental_report"/>

Is this possible in Odoo Studio? We're just on Odoo online
