Maybe you're thinking about this note from UT that proves that Olorin and Yavanna was at the same council, chosing the Heren Istarion:

Most of the remaining writings about the Istari (as a group) are unhappily no more than very rapid jottings, often illegible. Of major interest, however, is a brief and very hasty sketch of a narrative, telling of a council of the Valar, summoned it seems by Manwë ("and maybe he called upon Eru for counsel?"), at which it was resolved to send out three emissaries to Middle-earth. "Who would go ? For they must be mighty, peers of Sauron, but must forgo might, and clothe themselves in flesh so as to treat on equality and win the trust of Elves and Men. But this would imperil them, dimming their wisdom and knowledge, and confusing them with fears, cares, and weariness coming from the flesh." But two only came forward: Curumo, who was chosen by Aulë, and Alatar, who was sent by Oromë. Then Manwë asked, where was Olórin ? And Olórin, who was clad in grey, and having just entered from a journey had seated himself at the edge of the council, asked what Manwë would have of him. Manwë replied that he wished Olórinto go as the third messenger to Middle-earth (and it is remarked in parentheses that "Olórinwas a lover of the Eldar that remained," apparently to explain Manwë's choice). But Olórindeclared that he was too weak for such a task, and that he feared Sauron. Then Manwë said that that was all the more reason why he should go, and that he commanded Olórin(illegible words follow that seems to contain word "third"). But at that Varda looked up and said: "Not as the third;" and Curumo remembered it.
The note ends with the statement that Curumo [Saruman] took Aiwendil [Radagast] because Yavanna begged him, and that Alatar took Pallando as a friend.
