iTunes on my iPad Pro - how can I create/add/modify comments and create smart playlists ?

Hi, I am a 1st time iPad user.

I used to have my ITunes running on my Windows based computer and used it with an iPod Touch.

I added comments and used thses to create smart playlists with auto update.

It would have been great if it would be possible, while listening to my iPod Touch, to be able to create/add/modify/delete comments.

Some days ago I bought an iPad Pro and I notice that even though copying my complete iTunes database (including libraries) from my computer to my iPad I don't see the comments in my iTunes on my iPad Pro. I use the latest available version of iTunes.

Would you know : iTunes running on iPad Pro

Many thanks in advance.

with kind regards,
