No idea if this will help others ( as it is an old topic ), but this is what I came up with to solve a similar issue. I needed a hidden value that would act as a slug to pull in other templates.
Added a radio button control which asked the user to display or not to display this specific section. “Show Section” held the value of the hidden slug I needed to pull and would also be defaulted to this value, otherwise without the value the section would be skipped entirely and not shown.
my-slug : Show Section
0 : Don’t Show Section
