I'm familiar with how you can use a Workflow Action to auto-generate a Word Template document that references one of the out-of-the-box Word Templates and attach it to the record that the workflow has run against (example below)...
...but I can't set the Target to the record I'm running the workflow against when I run it against a custom entity and reference a system template I've created myself (notice the absence of a 'Funding Contract' option in the list of values below):
Any idea why this is? If I set the target to, say, the 'Customer' in the example above, it simply attaches the template with my XML placeholders rather than a populated document, so that's no good to me.
