I'm looking to include a snippet of JavaScript code that can be utilized across various pages and Templates, but may not be desired for all pages. This script loads in a simple widget similar to UserVoice,  The script snippet is not going to change, but if anything, there are only two configurable parameters when utilizing the snippet: url (required) and date start (optional). It's okay if these are hardcoded.

Based on the documentation, callouts are page-specific usually, but a module-driven callout seems like overkill here for a simple script include.Am I overthinking this whole thing?

Thanks in advance.
