How can we improve WHMCS?

When creating a quote for an existing client, you strictly have the ability to select that client. Frequently we have other users on the account asking for quotes, such as business partners or employees of the owner of the business. Currently we can work around this only partially by assigning the quote to the client, downloading the PDF, and attaching it to their ticket (which is assigned to the User).

However, the PDF itself shows ATTN to the client, not the user, which isn't accurate.

It would be great if, when creating a quote, we had the option to select a client, then also the user under that client that should be receiving the quote.
