extend account pages with child details

hello I use ultimate member that I find really well done.
but I have a simple question: I would like to create 3 or 4 child pages to the user page with each user mentioning their 5 favourite songs, albums, artists and music genre (and maybe more).

here is how the sitemap would look like:
– user
– songs
– albums
– artists
– genres

is their a simple way to do that?
