How can I add custom Javascript in JIRA Software OnDemand?

[A]

I have a custom JavaScript File which helps me to colour labels (which i have added as an extra field) in the list view of my backlog in JIRA Software.

However, how can I integrate this JavaScript File into my JIRA OnDemand?

+ As it is not the Server Version, I can't just upload a regular self-made plugin.
+ It's no longer possible to link it in the announcement banner (although that would be a dirty solution anyway)
+ I can't find a plugin on the Marketplace that would support me to define custom JavaScript Code for JIRA OnDemand .
+ I've read about the JIRA Connect Plugins, but it seems you can't create such a plugin for the sole purpose of adding a javascript file either.

I would really appreciate a solution! Thank you in advance!

Hi Alexandra, 

Unfortunately HTML and JavaScript in issue fields or even within the application are not supported in Cloud as per our Restricted Functions. Sorry about that!
