This article will focus on how you may include multiple document types within a submittal email. For more on sending submittals please refer here: Sending a Submittal Email and here: Crelate's Enhanced Submittal Email
To start, navigate to Settings>> Submittals and edit or create a new submittal template. To edit, simply double click to open the existing submittal.
Once within your template, you'll want to Configure Submittal Attachments
You may then select the sign to add different document types. If you're not seeing document types you'd like to include, refer here: Creating a Document Type. Once a document type has been added, you may refer back to this section to add that document.
Once additional types are added and you return to your submittal email, you'll notice those additional document types towards the right side of your screen (see below)
