Hello Newtguy!

I understand that you also need to add an option to customize the packing slip. While this isn't available, you'll want to consider the workaround shared by my peer. Create and customize an invoice, then rename it as Packing Slip.

1. Go to the Gear icon and select Custom form styles.
2. From the New style drop-down, select Invoice.
3. Click the Content tab. On the Form section, change the Form names to Packing Slip.
4. Tap Done to save it.

Also, I encourage you to send feedback about this. From the Gear icon, select Feedback.

I've added some links you can check. These will help you to make your templates more presentable:

• Import custom form styles for invoices or estimates

• Customize invoices, estimates, and sales receipts

Keep on posting here if you have other concerns. We'll respond as soon as we can.
