This is potenatially confusing to the end user, and may include things which we don't want to share with the customer. Upon reviewing all the articles I could track down, and some personal exploration of the Calls To Action section of the Admin, I've come to the conclusion that you can set up a layout per Call To Action Type (i.e. objective) but not control the layout based on whether the viewing the standard success plan vs a shared plan//internal vs external user.
Allowing this would enable better tailoring of what information is shown to customers we share our plans with, and prevent confusion by reducing unnecesary links.
