bootmenu is based on [menu], so you can use the same syntax. According
to this line from the IC repo:
https://github.com/interchange/interchange/blob/master/dist/lib/UI/vars/UI_STD_HEAD#L223

you should be able to set 

    indicator_page=page

which identifies the URL to use as the "page" field of the menu.
