Can we add model names when we do model comparison?

At the moment, when we run WAIC or LOO comparison of multiple models we get a nice data frame back, and can get a nice plot (like below).
But is there a way to provide more readable strings rather than just the model numbers? I guess this could be an additional argument in the compare() function in Either that or be able to give the Model class a descriptive name attribute?

I’ve looked at the code on GitHub and there’s nothing I can see that lets you do this currently, unless I’m mistaken. I could swear that I saw an issue on GitHub a while ago saying how to do this exact thing, but I can’t find it any more.

Yes there are two related PR that kind of been forgotten:

Currently, the workaround is:

    0: "Model1",
    1: "Model2"

comp_df = ([trace1, trace2], 
                      [model1, model2])
