Macros: Default value in "Collect Teammate Answer" form

I'm building a Macro and want to provide a default value in a "Collect Teammate Answers" form.

An example of how this could be used;
I'm building an escalation workflow. The teammate should pick from a "Priority" enum field (High, Normal, Low) - I want to have "Normal" pre-selected as the default field as this is what should be selected in most instances.
