STL 360 - Quick Access Toolbar ALT Number Defect

Can someone take a look at my screenshot please?

I have to do a lot of "replace picture from file" in my project. So I added that to the Quick Access Toolbar. But the keyboard shortcut is Alt 08.

How do you do an Alt and two numbers? 

I would love to have Replace Picture from File to be a keyboard shortcut so I can just press a single button on my programmable keyboard and go right into Replacing the picture.

Thanks!
