Homiletic directions from the Vatican to the Universal Church?

I've noticed that recently sermons in my local church have focused particularly on the life of Saints. I have observed this in other churches I've recently attended too (at least in 3 different churches). A friend of mine has also noted this in several churches **in a different continent** (and country, and language). (Incidentally, just yesterday I received a new edition of a Catholic magazine, and _voila_, the focus on Saints was forefront, and this seemed not connected to the upcoming feast of All Saints. Rather, it is asking the reader to write back which is his/her favourite saint(s).) All this might suggest that there was some form of informal or formal direction from the Vatican to focus homilies on the life of Saints. I've searched the Vatican website for this but cannot find anything about it. Sections of the Roman Curia I've checked include the [Congregation for the Doctrine of Faith](http://www.vatican.va/roman_curia/congregations/cfaith/doc_doc_index.htm) , [Congregation for Divine Worship](http://www.vatican.va/roman_curia/congregations/ccdds/index.htm) , [Secretariat for Communication](http://www.vatican.va/roman_curia/segreterie/segreteria-comunicazione/index_en.htm) , and many many other (full (?) list [here](https://w2.vatican.va/content/romancuria/en.html)) . So, my questions are: 1. Have you also noticed this in your local church? 2. If so, has there been a formal/public communication from the Vatican about it? 3. If not, then this might have been a form of private communication. Is there a precedent about this type of communications **regarding homilies**? Maybe this is a specific issue motivated by the upcoming All Saints' celebration (although I observed this earlier than October), or perhaps by the [March 2018 Apostolic Exhortation](https://w2.vatican.va/content/francesco/en/apost_exhortations.index.html#apost_exhortations) by the Pope, on the call to holiness, or both! All in all, the sudden change of focus might still indicate a formal type of direction from the Vatican.
