How to use a class instance implicitly

In my problem, if define a class with many property items as

classdef classname
   properties
      ProName1
      ProName2
      ...
      ProName100
   end
end

Then in my main script, I initialize an instance of this class as

para=classname

Then if pass this class variable para to another function, in order to use the terms in this class, I have to type para.ProName1, para.ProName2,....etc. Is there any way in the function, I can use the terms of para directly such as ProName1,ProName2..., without add the classname para in the function.

As far as I know, no. You can create one .m file per ProName. Then you don't need to write para.ProName2.
