Explanation of how to link to a structure from a structure I've searched these boards and haven't been able to find the answer to my specific question. 

I'm working on building my navigation, and I want to build it in a structure. It will be a multi-level navigation, which is why it makes sense for a structure. However, I've already built a separate structure for a sermon catalog that I want to keep separate from the navigation structure.

Basically, I want to be able to link to a separate structure within my navigation structure. Is this possible? Is there a better way to do this that I haven't grasped yet?

Navigation Structure Example

1.Home

2.About


Directions
Staff


3.Watch (I want this to link to my sermon structure)

4.Kids &amp; Students


Highschoolers
Middleschoolers
K-5th


EDIT: I've tried adding in an entry type to navigation and linking to the structure, but it won't let me link to the actual structure. Just entries inside the structure. Which is not what I want. Any thoughts?
I'll assume that 'watch' is a landing page in which you want to list out the various sermons from the sermons structure. In which case you can retrieve and display those in the 'watch' template using a for...in or a nav...in loop. For example:

{% set sermons = craft.entries.section('sermons').limit(null) %}
&lt;ul&gt;
    {% nav sermon in sermons %}
        &lt;li&gt;&lt;a href="{{ sermon.url }}"&gt;{{ sermon.title }}&lt;/a&gt;&lt;/li&gt;
        {% if children %}
            {% children %}
        {% endif %}
    {% end for %}
&lt;/ul&gt;


In your 'sermons' section settings you can then set the top-level uri to be:

watch/{slug}


And the nested uri to:

{parent.uri}/{slug}


In this way, you can set the uri's to match up nicely, with the index page as 'watch' and the sermon entries as 'watch/sermon-parent-slug/sermon-slug'
