Is it possible to disable one formatting pane slice based on the value of another?

When users select alignment: middle, the padding setting I provide them is not relevant and does nothing. It would be nice to disable it in such a case. 

Within the formatting model returned by getFormattingModel(), I can see a disabled property for the entire card, but I do not see such an option at slice level. It would help if someone could confirm whether it is possible to disable individual slices based on the value of other slices. Thanks!
