The first blessing in the Amidah is, of course, avot, where we acknowledge the patriarchs. What is the version of this text in nusach Yodeya? Where do we acknowledge our additional patriarch? Do we say elokei Avraham, elokei Yitzchak, elokei Yaakov, elokei Yitzchak, to preserve the order? Or is that confusing and instead we say ...elokei Yitzchakim? Or maybe we add elokei Yitzchak Moshe? Or do we not modify this passage, and we instead acknowledge the last patriarch somewhere else?
I've been unable to obtain a Yodeyan siddur, but I'm hoping that one of you can tell me what the correct practice is.
(I'm aware that there are other places in davening where we list the patriarchs. I'm focusing on this very prominent one, but a general answer that applies to all of them, if such exists, would be great.)
