Get Invoice Notes

Hi!

Can I get Notes for Invoices using this Api? : https://www.zoho.com/books/api/v3/#Invoices_List_invoices

Now I'm using the method above, and then for each invoice I call the method below to get the " Notes" field: https://www.zoho.com/books/api/v3/#Invoices_Get_an_invoice.

I have very strong performance problems because the user waits very long.

Can this somehow be optimized in a different way?

Thanks
