In case anyone is still confused (like myself) about using 'red symbols', I found this VwKB Tech Tip video:
I understand the usefulness of Red symbols for pre-setting attributes and parameters as michaelk pointed out, but I don't see how it answers the original poster's question:
Once placed, a Red symbol is just like a regular Door PIO and it is not linked to others of the same type, so you would need to keep track of which doors are type ID-01 -vs- ID-02. Which Magic Wand settings would allow you to select only doors of type ID-01 so that you could make global changes to only that door type?
