Sort Project Custom

There are only two ways to sort a project from recently added or A-Z. It would be nice If I could move them around to an order that I want them in. Like adding my favorites at the top. Most of the time I have more than 10 potential songs Im interested in and its overwhelming. It would be nice to arrange them so I have favorites at the top or even If Im trying to pick a few songs I could put the two or three that Im thinking of together in succession to make my life easier.
