I created a new field in the crm.lead template and I want to increment the context of the button responsible for generating the quotation from the opportunity.

https://github.com/odoo/odoo/blob/2569bcc11d5dfc0e09adc3495ca51aefdd375f70/addons/sale_crm/views/crm_lead_views.xml#L9

So far I have created the field in the models crm.lead and sale.order

class CrmLead(models.Model):
    _inherit = 'crm.lead'

    vehicle_id = fields.Many2one("workshop.vehicle", string="Vehicle")

class SaleOrder(models.Model):
    _inherit = 'sale.order'

    vehicle_id = fields.Many2one("workshop.vehicle", string="Vehicle")

And managed to take the value of vehicle id to the sales order. However, overwriting the whole context of the button responsible for the quote generation.

<record id="workshop_vehicle_crm_opportunity_form_view_inherit" model="ir.ui.view">
       <field name="name">workshop.vehicle.crm.opportunity.form.inherit</field>
       <field name="model">crm.lead</field>
       <field name="inherit_id" ref="crm.crm_case_form_view_oppor"/>
       <field name="arch" type="xml">

           <button name='%(sale_crm.sale_action_quotations_new)d' position='attributes'>
               <attribute name="context">{
                   'search_default_partner_id': partner_id,
                   'default_partner_id': partner_id,
                   'default_team_id': team_id,
                   'default_campaign_id': campaign_id,
                   'default_medium_id': medium_id,
                   'default_source_id': source_id,
                   'default_vehicle_id': vehicle_id,
                   }
               </attribute>
           </button>

           <xpath expr="//field[@name='partner_id']" position="after">
               <field name="vehicle_id" string="Vehicle"/>
           </xpath>
       </field>
   </record>

Is it possible to just increment the context of this button in the module sale_crm?

Thanks,
