Is it possible to have a hierarchy of alternatives besides a criteria hierarchy?

What if the car model/example I would like to add cars from others vendors besides Honda?
That would be the same in the "Choosing a Leader" example if we would like to have more candidates and group them according some characteristics.

In these two cases I would like to first rank such new characteristic (e.g. vendors) among themselves. Then I would rank the alternatives (e.g. cars/leaders) inside their groups. Finally I would apply the groups' weight to the weight of each alternative in order to get the final weight/priority.

I imagine all of it would be like adding "children" to each "alternative".

Does your R package support it in just 1 time run? Or I would need to run it 2 times and weight the results?

Thanks in advance, and congrats for the package!

Good question. I don't think the package supports this out of the box. The only thing I can think of right now is to create functions that return attributes as a function of which group an alternative is in. Not exactly what you had in mind, but you could achieve the same result.
Also, I don't think it would be super hard to build that into the package, though I am not sure that this is a frequent use case for practitioners. Though very open for pull requests.
