Feature Request: play sentences from filtered collections

After a particularly difficult day with a lot of new words, I often like to filter the collection search to show all those I have 25% Mastered and review them. It would also be nice to have the option to play them again as well. One currently is able to play sentences drawn from a collection; perhaps there can be an option to play sentences from a filtered collection too. (Right now a workaround is to add all sentences to Favorites and then play it; but it seems a bit roundabout, because you have to keep modifying Favorites.)
