Thank you for your reply. However, while Re'eh reflects Chodesh, Ki Teitzeh does not, as it does not show doing the entire Noach Haftarah. Can that be corrected?

Is it possible to query the REST API for the Calendar to pull multiple traditions for Haftorot? For example, in Parshat Re'eh, most synagogue I know read Shabbat Rosh Chodesh, and combined Re'eh and Ki Teitzeh.
