Is there a way to sort the Items list in numerical order rather than alpha?

We want to use Zoho Invoice to invoice our HOA members for the Lots they own in our neighborhood. Some members own more than one lot. We've created an items list. The Description field starts with the Lot number, e.g. Lot 1, Lot 2, etc. When creating invoices, the Items list is sorted alphabetically so Lot 11 comes right after Lot 1 followed by Lot 12, etc. 

This makes it difficult to be certain that we've invoiced for every Lot. It would help if the Items list could be sorted in numeric order.

Thank you.
