In Account Settings > Firm Defaults > Petition Defaults, there is now an "Account Numbers” option with the following two checkboxes:
Last 4 Digits (default selection)
Full Account Number
If you go into your settings and check the box for "Full Account Number," a box for "Add Full Account Number” will be checked automatically in the sections for entering new claims in NextChapter, allowing you to type in full account numbers when editing a claim. This option will not override information in existing claims, only new claims entered after adjusting your settings.
