AI generated answer (using internal Slack threads):

Based on the conversations, it appears that the Messages sub list on opportunities is inherently static and cannot be directly modified or dynamically updated through scripting. This behavior is by design, as the sub list is meant to hold user communication that is not editable through standard operations. In the conversations, users discuss the limitations of static sublists in NetSuite, specifically mentioning that they cannot be updated via client scripts in the UI. One user points out that what might appear as a dynamic update in the NetSuite UI (such as the open invoices list in customer payments) is likely the list being rebuilt, not altered, possibly through a page reload. Another user emphasizes that NetSuite does not use SuiteScript to build its UI, and therefore, SuiteScript may not be able to replicate all the functionalities seen in NetSuite. In terms of customizing a sublist, the conversation suggests that the options are limited. The "customize" button may not be available for a custom (scripted) sublist, and the addButton and MarkAll/Refresh might be the only options available. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
