I need to make different sequence name if maintenance_team_id = 1 or 2, etc

Here is my sequence code in bold. For now my sequence is applied to all maintenance_team_id

But i want to make different sequence based on each of maintenance_team_id

@api.model_create_multi
def create(self, vals_list):
    for vals in vals_list:
        vals['name'] = self.env['ir.sequence'].next_by_code(
            'maintenance_id_1') or _("New")
    # context: no_log, because subtype already handle this
    maintenance_requests = super().create(vals_list)
    for request in maintenance_requests:
        if request.owner_user_id or request.user_id:
            request._add_followers()
        if request.equipment_id and not request.maintenance_team_id:
            request.maintenance_team_id = request.equipment_id.maintenance_team_id
        if request.close_date and not request.stage_id.done:
            request.close_date = False
        if not request.close_date and request.stage_id.done:
            request.close_date = fields.Datetime.now()
    maintenance_requests.activity_update()
    return maintenance_requests
