can we add array of nl expressions with name in macro

using JuMP
mm=Model()
for i in 1:5
       @NLexpression(mm,pp[i],i)
       end

ERROR: An object of name pp is already attached to this model. If this is intended, consider using the anonymous construction syntax, e.g., x = @variable(model, [1:N], …) where the name of the object does not appear inside the macro.
