Is it possible to include both the Catholic liturgical year ring and the Byzantine (Gregorian) liturgical year ring in the same Sermon Manager? I'm asking on behalf of a dual rite priest who regularly uses both - one for one Sunday a month + major feasts, the other for the remaining Sundays.
Note that dual lectionaries are also used when a church uses the RCL and their school uses the Narrative Lectionary and/or the Season of Creation.
