here is action which the button is calling.

I want to pass data from my O2M lines to another form's O2M lines on a button click which is of type action. Is there any way to do that? also this button and action is odoo's default

<record id="sale_action_quotations_new" model="ir.actions.act_window">
 <field name="name">Quotation</field>
 <field name="res_model">sale.order</field>
 <field name="view_mode">form,tree,graph</field>
 <field name="domain">[('opportunity_id', '=', active_id)]</field>
 <field name="context">{'search_default_opportunity_id': active_id, 'default_opportunity_id': active_id}</field>
</record>

this is the button 
<button string="New Quotation" name="%(sale_action_quotations_new)d" type="action" class="oe_highlight"
    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}"/>
