Hi!
Yes, this is possible.
You must create a subvi. Make your normal vi (e.g. the vi for button 1) and make a subvi highlight everything you want to get as a subvi (toolbar) edit -> create subvi. I thought, if you save this under "user.lib" folder, you can see yours subvi (after restart lv) in the functions of the diagram ( all functions -> own library).
Now you can insert this subvi in your main vi (with only some buttons), and wire this with your button.
I'm no longer sure if you have to make a special setting in the vi options...
Maybee look at this:

Edit:
If you would like to "pop up" the vi you have to make this settings:
