Set all reminders with no due date to due today

I’ve been trying to create a shortcut which will find any reminders which do not have a due date, and set them with a due date of tomorrow, but I can’t see any way to only apply it to non-dated items… the closest I can find is to say “Is not X date” but then it applies the changes to all other dated items. Is there any way to do this?

For reference I’m using this shortcut as the basis for mine:
