Smarty assign value to variable inside included template - php

Question

I have a listing item template as below:
<div class="listing-item">
<div class="photo">{$thumbnail}</div>
<div class="title">{$name}</div>
<div class="price">{$price} {$currency}</div>
<div class="location">{$city}/{$town}</div>
</div>
I'm including this template from another template file, and assign it into a variable named listing_item, as shown below:
<div class="listing-box-container clearfix">
{include file="common/product/listing_item.tpl" assign=listing_item}
</div>
Now i have var a variable named listing_item that holds template for single listing item.
I want to assign value to variable inside listing_item like:
{assign var="$listing_item.thumbnail" value="Sometown"}
I'm not passign values while i'm including the template because i want to use listing_item multiple times so i dont want to load it everytime i need it.
The idea here is include the template once, and assign values & echo where it needed.
So, how can i assign value to variable inside a template which has already been included and assigned to a variable?
Or, what is the best practice to archieve my needs in smarty?
Any help will be highly appreciated

If You are using smarty3 You can use this constuct:
{$listing_item = [
'thumbnail' => 'some_thumbnail',
'title' => 'some_title',
'price' => 'some_price'

More about variables syntax here http://www.smarty.net/docs/en/language.syntax.variables.tpl
Now pass it to the template:
<div class="listing-box-container clearfix">
{include file="common/product/listing_item.tpl" listing_item=$listing_item}
</div>
And within the template use:
<div class="listing-item">
<div class="photo">{$listing_item.thumbnail}</div>
<div class="title">{$listing_item.name}</div>
<div class="price">{$listing_item.price} {$listing_item.currency}</div>
<div class="location">{$listing_item.city}/{$listing_item.town}</div>
</div>
