How to specify RunDeck WinRM connection settings for a given host?

We've configured a RunDeck project to use the Foreman hosts url to get a
list of machines, and it's working quite well. I know from here
<Rundeck Integration - Foreman> we
can export facts as tags and set a custom username, but when trying to
setup jobs to use WinRM we're having trouble setting the connection
parameters like connectionType. We want to use WINRM_INTERNAL but it
ignores that parameter as we have configured it in RunDeck and uses WINRM
instead, and then the connection fails.
