Hello
The best solution to this case you mention is to create a single contact card for a generic "once-off" supplier to represent you Sundry Supplier, and give this an easy to remember code.
Each time you create an invoice for a sundry supplier, you will then use the code create above. On the purchase invoice record, the default name of the contact would pull through to the "Name" field. You can then overwrite this name with the name of the supplier you are actually dealing with.
Using the methodology above, you can create Invoices for a sundry supplier without creating a new contact card each time.
Best regards,
