Is it possible to make separate collections of books? / Kun je aparte collecties maken binnen LT?

Does anyone know whether it is possible to build separate collections within your own collection of books? I would like to separate Fiction and Non-fiction books and Borrowed books and in my own possession.

Fiction and non-fiction can be 'separated' by tags.

Thank you, I know that but I find that a little bit insufficient. It would be nice to have a kind of separate 'show' collection about a certain subject like gardening, cats, art, etc. I also feel the need to separate borrowed books from my own. I've noticed that many people have mentioned their books from the library and of course you can say that you have read the book but is it really yours? It is only temporary in your bookcase. Is LT about all the books you have read or about the books you own. A difficult question and now I think about it it doesn't really matter. In any case LT is great in learning about which books fiction / non fiction exists.
