How to pass custom context from another model to listview all elements added in a many2many

Question

Model A to Model B have a many2many relationship , in listview how can i pass context to each row added and use the context to pass data to button within the listview for each row added

Here is the code

    class ratecard_multiple(models.Model):
    # pudb.set_trace()
    _name = 'ratecard.multiple'
    _rec_name = 'display_name'

    scheduled_for = fields.Integer(string='SCHEDULED FOR', default=1, track_visibility='always', store=True)

    multiple_ratecard_id = fields.Many2many(comodel_name='ratecard.sin.radio',
                                            relation='ratecard_multiple_singular_rel',
                                            column1='ratecard_multiple_id',
                                            column2='ratecard_sin_radio_id',
                                            string='RATECARDS')

class ratecard_sin_radio(models.Model):
    _name = 'ratecard.sin.radio'
    _description = 'RATECARD SINGULAR RADIO  '

I want to pass the value of scheduled_for to each row added in multiple_ratecard_id
