It is possible to create stacks in the Layer for all invoices and invoice payments that have not been reconciled.
To create stacks such as these, create a New Template from the left-side bar from any Work Stacks view and select Invoice as your type.
Make sure to check the No box for the Reconciled filter.
Reconciling invoices from the work stack
