How often has the Pope asked all Catholics to pray the Rosary?

In the history of the Catholic Church, I know there's been extra days of fasting and prayer called for by the Pope and Bishops, but other than prior to the Battle of Lepanto and today (March 19th 2020, The Solemnity of St. Joseph) at 9:00 PM Rome Time . Has the Pope ever asked all Catholics to pray the Rosary in unity (or as simultaneously as possible prior to mass communication and computerized synchronization)?
