IDE Hint for reflection method parameters

I have a function that might be called like this

this.InvokeFn("MyFunction", param1, param2);

Internally, this function is finding a function named "MyFunction" on "this" that takes two parameters. I can define this "MyFunction" but the IDE says it isn't used. I don't suppose there is a way to tell the IDE what this function is doing to provide better hints? I note that the Unity plugin does this for the Invoke calls that are part of the Unity API
