Hi CassG
Welcome to the Community Forum. At this stage, the Items List window does not have an option to update all items. However, you can export your Item List and remove the 'I Inventory' option in Excel, then import the updated information back into AccountRight.
For instructions on how to update items through export/import click here: Updating items.
For details on the import fields click here: Import and export fields.
Hope that helps.
