From the Safer Haminhagim: [Every day from Rosh Chodesh Nissan until the twelfth of the month, usually after Shacharis,] one reads the passage [from Bamidbar 7-8:4] that describes the offering brought on that day by a particular Nasi, or tribal prince, for the dedication of the altar of the Mishkan. [In common parlance, each day's passage itself is often referred to as “the Nasi.”] This daily reading is followed by the prayer which opens with the words yehi ratzon (and which appears in Siddur Torah Or [as well as in Siddur Tehillat HaShem, p. 371]). This prayer is recited even by a Kohen or a Levi [despite its seeming relevance only to tribes other than the Tribe of Levi]. [284]
