Joystick support via SDL2 library?

If we had the Engine Source available then we could use:

#if ENGINE_MINOR_VERSION<7
StructBuilder.AddChildContent(LOCTEXT(“KeySearchStr”, “Key”))
#else
StructBuilder.AddChildContent(LOCTEXT(“KeySearchStr”, “Key”).ToString())
#endif

=8-O

But it´s an “workaround” that seems to work -> only with engine source.
