I want to inherit workflow based on user requirement.

For example original code

        <record id="t7" model="workflow.transition">
            <field name="act_from" ref="act_confirm"/>
            <field name="act_to" ref="act_draft"/>
            <field name="signal">draft</field>
            <field name="group_id" ref="base.group_hr_user"/>
        </record>

In the above code I want to comment the following line <field name="group_id" ref="base.group_hr_user"/> because the action for the following  tranisition only possible for user belongs to "Human Resource/Officer". I want to customize the following action to all users.

So that I inherited by following code,

        <record id="hr_expense.t7" model="workflow.transition">
            <field name="act_from" ref="hr_expense.act_confirm"/>
            <field name="act_to" ref="hr_expense.act_draft"/>
            <field name="signal">draft</field>
        </record>

After I update the following code in my customized module,It doesn't give what I want.Original code only running.

Is it possible to inherit workflow.??. Or I have to change in Original source code.??.
