Could Package "mediate" support multi-categorical treatment?

I could find arguments 'control.value' & 'treat.value' in the function mediate, it seems that the function could support binary treatment. I am not sure whether mediate can support multi-categorical treatment (# groups >= 3) as well. Thank you for your help in advance!

From what I understand, yes. In example 1: Linear Outcome and Mediator Models of mediate function documentation, the categorical treatment demonstrates this. You just need to specify the parameters control.value and treat.value.
