TL;DR
An icon used in blueprints which, when the blueprint is instantiated, becomes a unique string or icon not used elsewhere in that surface. For example, replacing the placeholder icon with a name chosen from the supporters list like for trains, platforms, etc.What?
I have been working on a logistics system blueprint book. One annoyance is I must manually assign a unique icon every time I place the blueprint down, for certain blueprints. These icons must always be unique to the instance of the blueprint on that surface. Specifically, they are used for train stop names and orders on included trains referencing the station in the blueprint. It would be very, very helpful if it was possible to have a parameter that would, when the blueprint is placed, change (in all instances it appears in the blueprint) into a unique icon/quality combo, or a unique text string (e.g. supporter's name) that does not exist already on the current surface. My use case is trains that leave their blueprint to collect items based on a circuit interrupt, and then return to the station they departed from.I am able to provide these blueprints if requested for context
