How can i add a rich text field before the product tables?

Hello there,

Im fairly new to this, i installed the v5 and is working, i already sent a quote for testing. Now i only need to have a somewhat basic proposal functionality, like to have a rich text field before or after the product table,

But i will appreciate a little help. Txs in advance.

EDIT:
I ended up adding all my html code to the body segment. Regards.

Hi,

One option may be to configure a custom invoice field and then position on the PDF using a custom design.
