Fabled to add specials

There is not an issue related with this feature request.

Describe the solution you'd like
I have tried to add specials like "signals" to Fabled characters using the "global" optional attribute but it doesn't seem to work. Maybe this has some relation with #141.

Describe alternatives you've considered
I dont think there are alternatives to this right now.

Additional context
An example for this is when a Fabled adds an object that can be distributed to any character or player and instead of using the "Custom" signal, we could use a predesigned signal using this.

Yes, Fabled signal cards are currently unsupported, but I guess I could add this support rather easily.
