How do I globally customize the Invoice Sales Orders screen?

AI generated answer (using internal Slack threads):

To globally customize the Invoice Sales Orders screen, you would typically use the 'Customize' button that is available on the screen. However, it's important to note that these customizations are user-specific and will not apply to all users at once. Unfortunately, there isn't a built-in way in NetSuite to apply these customizations globally to all users. Each user would need to apply their own customizations individually. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******

It's not a custom form AFAIK. I have narrowed down the options for doing this to three: 1. Customize to add fields you want. Not sure if this lets you add line-level fields or just body fields. It's been a while since I looked at it. 2. Create your own suitelet, or obtain one, that does the all the same things (and maybe more), but presents the form the way you want (the most work/programming unless you can find one already built). 3. Add a custom field that alters the form after it loads using inline javascript (very unsupported).
