The feature of showing investment inquiries form submissions in the Deals Pipeline and sending email notifications to the account owner already exists, but it may not be activated in your account. To activate it, you need to select the "Deals added by Investment Inquiries Form" stage setting in Hub. If you need assistance with this, you can give permission for the change to be made in your account over Slack. It's worth noting that this functionality was supposed to be the default for new accounts, but it may have been changed recently. However, it has been reset for accounts, so it should be working for anyone else who encounters this issue.
