driver_store_id = fields.Many2one(
    'res.store',

)
<field name="driver_store_id"
       attrs="{'invisible': [('collection_required', '!=', 'yes')]}"

Normally, driver_store_id shows only stores from the user’s current company,

I want to auto-suggest (auto-fill) a driver store that may belong to:

the same company or any other company (ALL companies).

I want to avoid computed fields, stored helper fields, or heavy domain computations, as they may cause performance issues.
