Unity exports my derived class, but not its base class (C# OOP) - Is there a workaround?

I'm having trouble exporting a prefab with all its dependencies, specifically the base class of my derived class.

For example:
Let's assume I have an Engine class and a SpecialEngine class w$$anonymous$$ch is derived from the Engine class.
I add the SpecialEngine component to a gameobject.
I create a prefab from the gameobject.
I right-click my prefab and choose "Select Dependencies".

It selects the SpecialEngine class but not the Engine class w$$anonymous$$ch means that if I export the prefab with the suggested selection and import the package into a different project it will not be able to compile due to the missing base class.

Does anyone know of a good workaround?

I guess I could attempt to write an Editor script that loops through the components of the main gameobject in the prefab and all its c$$anonymous$$ldren and adds the base class files to the depency selection.

If someone has already written such a script, please share it :)
