When putting together a service of Matins we can choose the option of "common" or "lectionary" but, nothing appears when "lectionary" is selected.
This was one of those things you were working on, and there is no rush. I would certainly use the option if it were there.
For Matins services in Easter I managed to get by with having my secretary scan in the lectionary antiphon from the Altar Book and pasting that into the bulletin.
