Make the invoice due email aware of package

[Rocketz]

Is there a way to make the invoice due email aware of which package it's sending the email for? 

I want to add a small icon, which is unique to each package, in the invoice email to make it look nicer. Can this be done?

The service_id is available via line_items, see https://docs.blesta.com/pages/viewpage.action?pageId=4161679#InvoiceDelivery(Unpaid)-SupportedTags but it may not be possible to determine what package the service is linked to within the email template. You can use the tag {% debug %} to see all of the data that's available to the template. YOU SHOULD BE CAREFUL THOUGH, not to send out an email with this tag to any customers. There could be sensitive information in the output.
