Just to give you some context, on my Woocommerce site, a customer can add multiple subscription items to the cart before checking out.  I want that same functionality in my zoho subscriptions that doesn't send a customer multiple invoices.   Also, I deal with channel sales and send customers a quote for SaaS subscription items, which they can convert to an invoice and pay.  I would like to either be able to use that same process for subscription items with auto renew OR I'd like to be able to create subscriptions without payment information that automatically invoice customers for renewals in advance of their expiration.
