Magento – Targeting multiple layout handles in layout XML

layout

I have a custom controller accessed at the path /custommodule/customer/info which is loading the 2columns-left.phtml template on the root node as follows:

<custommodule_customer_info>
    <reference name="root">
        <action method="setTemplate"><template>page/2columns-left.phtml</template></action>
    </reference>
</custommodule_customer_info>

What I would like to do is update the root template for customers who are not logged in, something such as:

<customer_logged_out>
    <custommodule_customer_info>
        <reference name="root">
            <action method="setTemplate"><template>page/1column.phtml</template></action>
        </reference>
    </custommodule_customer_info>
</customer_logged_out>

I understand that I can't target multiple layout handles in this fashion, but the intent should be clear; update the root template for this layout handle while customers are not logged in.

I had thought that I could target my controller's handle with the following:

<customer_logged_out>
    <reference name="custommodule_customer_info">
        <reference name="root">
            <action method="setTemplate"><template>page/1column.phtml</template></action>
        </reference>
    </reference>
</customer_logged_out>

This indeed does update the root template with the 1column.phtml template, but it is doing so on what appears to be all pages instead of just the page targeted in my reference node.

I have tried several permutations of this layout update, but none seem to work. How can I target this one layout handle while at the same time using the customer_logged_out layout handle?

— edit —
To be clear, this is actually a third-party module.

Since you are using your own controller you don't need to only use the default handles. Based on the logged in status you could add in your infoAction method

 $this->getLayout()->getUpdate()->addHandle('mymodule_customer_info_logged_in');

or

 $this->getLayout()->getUpdate()->addHandle('mymodule_customer_info_logged_out');

and then in your layout.xml file use

<mymodule_customer_info_logged_in>

and

<mymodule_customer_info_logged_out>

-- addition after your edit below --

Seeing that you don't want to edit the controller (since it is a 3rd party extension), I would create a separate extension that only observes controller_action_layout_load_before

    $update = $observer->getEvent()->getLayout()->getUpdate();
    $handles = $update->getHandles();

    if (in_array('custommodule_customer_info', $handles)) {

        //code to add the custom handles based on login
    }
