Insert Quote into Proposal?

I see from the docs that I need a quote to build a proposal, but the Proposal doesn’t seem to include the quote when I download, email, or view it from the portal.

How do I get the quote inserted into the proposal?

Found another thread saying this isn’t supported.

It’s disappointing that I’m going to have to go back to making PDFs in Word to get a complete proposal out to a potential client.
