Custom View Modes

Guys, I need a hand. I have created two new "View Modes" on View -> Current
View Mode -> Define View Modes (sorry if it doesn't exactely match the names
in English, I'm using a local Office 2007). So now I can select these two
modes from the list where there were "Messages", "Last seven days", "Unread
Messages on this Folder", etc, by default.

Is there a way I can put these two modes I've created on the toolbar? I can
put the "Current View Mode" there, which is a drop down menu that contains
all those default options and my two custom. But I would like to have direct
access to my custom view modes in the toolbar, like a button. I have searched
for them all over the personalization options but I couldn't find them there,
only the "Current View Mode" menu. I was thinking about creating a macro that
would switch between these two modes (and then I know I could put it as a
button there) but I realised I don't know how to do it properly.

Thank you very much for your help.
