Hi,
I think extensive editions like the Cortot ones of Chopin are not too frequently appearing. They might be exceptional, in a way.
So, we might, perhaps, to "step one level back" , and search for "instructive editions".
An instructive edition should exist of the Fantasy op. 17, of Schumann, but since I don't have it, I don't know how eleborate the instructions are.
Klavier-Werke von Robert Schumann. Erste mit Fingersatz und Vortragsbezeichnung versehen Instructive Ausgabe. Nach den Handschriften und persnlicher Ueberlieferung herausgegeben von Clara Schumann. Dritter Band (No. 14-19). No. 14: Koncert ohne Orchester. Dritte grosse Sonate. F moll. Op. 14 No. 15: Kinderscenen. Op. 15 No. 16: Kreisleriana. Op. 16 No. 17: Phantasie. Op. 17 No. 18: Arabeske. Op. 18 No. 19: Blumenstck. Leipzig u. Brssel, B&H (V.Nr. 619) [ca. 1880]. 119 lithogr. S. fol. Ln. [RARE PRINTED MUSIC] / Schumann, Robert (1810-1856)
In English ( I summarize ): It's the 3rd volume, Edited by Clara Schumann, of R. Schumann's works, being an instructive edition, and following and showing the fingering and performance-indications given in the manuscripts and / or taken from personal tradition.
There's newer, by Wilhelm Kempff revised version ( e.g. 1986 ) of it, too, in some libraries. Perhaps you can get it somehow.

But as we know, Alfred Cortot wasn't only an expert in Chopin, he also was a Schumann-fan. So he did this:

which should be to obtain somehow, too.
But I don't have it either. Perhaps you can have a look at one or both of the two, and find out how extensive / elaborate the annotations are.
And perhaps others have additional sources / versions / editions which should be mentioned here.
Cordially, 8_octaves!
