I recognize the convenience of grids or alternating lines on an invoice template, @RY12. I'll walk you through submitting a feedback request to have this feature.

Adding lines to separate invoice details is currently unavailable. You'll want to share this idea with our Product Developers to have this reviewed for future updates.

Here’s how:

1. Go to the Help icon at the top menu.
2. Select Send Feedback Online and then click Product Suggestion.
3. Enter your request, then tap Send Feedback.

Track your suggestions through this website or visit our blog to keep up with recent events and developments.
