Invoice splits due to sales order number being different.

[a123456]

We are trying to setup invoicing by sales order (SO). We would like to combine multiple SO(s) into a single invoice. All pertinent information is identical in both SO documents. Is it possible to stop splitting invoices due to sales order numbers being different? Below is the error message resulting in the split invoice. Any help would be greatly appreciated.

Thank you for your assistance.
