I’m using a scholarly edition of a verse text. The edited text itself is customarily referred to by verse number rather than by page, while the editorial part of the book is paginated normally. To spare me writing "p." or "v." manually every time I refer to either part of the book, I made separate entries for each with the according setting in the pagination option where it differs from the default "p." However, this also causes the book to appear twice in my list of references, and textcite produces "Schröder (1895a)" and "Schröder (1895b)," which does not sit well with my advisors.

MWE:

My question is, thus, if there is a straightforward way to only print one entry "Schröder (1895)" in both in-text citations and the bibliography, but still automatically get "p. XXX" or "v. XXX":

Schröder (1895, p. 42), Schröder (1895, v. 1234)

I already tried to add options = {skipbib=true} to the @inbook entry, but that does not have the desired effect and only omits it from the bibliography while keeping the letters on the year. If there’s no straightforward way to solve this, I could simply make the default pagination style for the @book entry verse and manually put p.~ on the few occasions I refer to the editorial part. I thought I’d still post this question because it strikes me as an interesting problem that I haven’t yet found a general solution to.
