A boolean indicating if you would like to use internal names for customizations.
Typically the Label of a customization is shown when surfacing tables for custom records, and columns for custom field. This is done for ease of use so that things appear as they do in the NetSuite UI. However, it is technically not guaranteed to remain the same. If someone goes into NetSuite and modifies the label, it will cause the custom field or custom record to change name in our tool. Setting UseInternalNamesForCustomizations to false will instead cause the internal API names (which cannot be changed) to be surfaced for these tables and custom fields instead.
