Is it possible to use two different objects in one template? Let say I write template that applies to res.partner, then I use this object to build letter. But in that same letter I want to add list of products that are in my database. So I would use product.template. as res.partner does not have direct link to products I don't see a way where I could use like:

object.[link to product.template] So I would like to use it like:

<p>Hello ${object.name}</p>
<p>Here is our product list:</p>
%for name product_template.name:
<ul>
<li>${name}</li>
</ul>
%endfor

Is it possible to do in email template?..
