Add line to comment in Visual Studio C++ - c++

Question

I'm looking for something rather specific.
Let's say I define something like a variable, and add a comment to it.
#define ARDUINO_READ_Q0 //Read pins 22-29
Now, any time I start typing ARDUINO_READ_Q0, it pops up in Visual Studio's list of available values, and when you hover over it, it comes up with a tooltip saying "Read pins 22-29"
Is there any way to add a line to this tooltip? I thought of something like this:
#define ARDUINO_READ_Q0 /* Read pins 22-29
Return 1B */
However, I would prefer for it to remain on a single line when I define it.
To give you an idea of what I'm trying to do, imagine something looking like this:
#define ARDUINO_READ_Q0 // Read pins 22-29 /n Return 1B
This way I can say "next line" without making the mess of having two lines per #define.
It's sort of a formatting preference. I'm about to have a lot of #defines.

If you are using Visual Studio 2013 there are special XML tags that you can use to do this.
/// <summary>Read pins 22-29</summary>
#define ARDUINO_READ_Q0
This will display "Read pins 22-29" in the Intellisense tooltip when you hover the ARDUINO_READ_Q0.
You can find more documentation details on MSDN:

Note: This may work on older version of Visual Studio but I only have 2013 have on my laptop at the moment.
