Classical Music menus and Custom Browse templates

I have setup my browse menus for classical music according to the 'Setup browse menu for classical music' wiki guide and have created several seperate menus as follows:

Classical Music > Composer > Work
Classical Music > Composer > Conductor > Work
Classical Music > Composer > Soloist > Work

These work as expected but it would be much neater if I could 'nest' all the menu choices after Composer together so that the user would see a further menu choice after selecting their desired composer... something like this:

Classical Music
Can anyone tell me if it is possible to create this using existing Custom Browse templates and if so give me so advice about how to do it please?
If there are no templates but it is possible, how much effort would this take, and could someone with very limited xml/SQL knowledge be able to do this?

Thanks in advance
