Do custom Eula bags always come with a padded strap?

I've already designed a Custom Eula X-Small messenger bag, and want to know if it will come with a padded shoulder strap? Seems that some bags do come with a padded straps, while others don't--and this one might be an exception since it's custom. Also my online research seems to show that 2008 bags should come with padded straps, while older ones don't.
