Automatic refactoring of function parameters on class attributes

Hello, I'm new to PyCharm)

I have this question. Suppose I have a function with parameters:

def func(param1, param2, param3, param4, param5):
    
    
    # do something with this params. It is a really long code.
    # but for example we suppose it will be

    return param1 + param2 + param3 + param4 + param5

And then I suddenly realized, the parameters are a single entity and it would be convenient to make a class that will have parameters.

class MyClass(object):
    """docstring"""

    def __init__(self, param1, param2, param3):
        """Constructor"""
        self.param1 = param1
        self.param2 = param2
        self.param3 = param3

Is there any special automatic refactoring to replace the parameters:param1, param2, param3 in the function code to MyClass attributes?

To replace all 

param1 --> MyClass_obj.param1
param2 --> MyClass_obj.param2
param3 --> MyClass_obj.param3

in our code.

To get this result

def func(MyClass_obj, param4, param5):
    # do something with this params
    # for example
    return MyClass_obj.param1 + MyClass_obj.param2 + MyClass_obj.param3 + param4 + param5

or here is such a "preparatory result 2"

def func(MyClass_obj.param1, MyClass_obj.param2, MyClass_obj.param3, param4, param5):
    # do something with this params
    # for example
    return MyClass_obj.param1 + MyClass_obj.param2 + MyClass_obj.param3 + param4 + param5

I tried to do the usual rename refactoring, of course it detected an error in the name(the presence of a dot from the class) and did not allow me to do this.

Is it possible to implement such refactoring automatically in PyCharm?

Now I can only do this with the help of Multiple selections.
I'm moving my function to a separate python file and typing by Multiple Cursors in all param1's occurrences.

param1 --> MyClass_obj.param1

Then I do the same with another parameters: param2 and param 3.
I get the result "preparatory result 2" by this approach =) And then I do

But it seems to me that there is probably some special automatic refactoring for this purpose =)
