I think what Peter refers to is that there is no way to transfer only the Marker settings from one Door to the other.
You can use CTLR-ALT-click to transfer attributes, but that will transfer all attributes, including the Marker settings.
But what if you Door is fine with all its settings you just want to transfer the Marker settings from another Door? It is only possible to do by setting all values of the Marker one by one. Door/Window Markers do not have Favorites.
The only workaround I can think of is that you open the Marker for editing (use the Open by Subtype command - its menu command is not part of the default Work Environment, but it can be found on the Edit GDL Library Parts toolbar. Then set the default parameters to your liking and save it under a new name.
Do this as many times as you need different Door Markers.
Then you can do what Matthew wrote: select a different Marker which will come in with its default settings, which are the ones you set to your liking.
