I have a solution, if you never use this as a “grouped” citation. See the attached image of the citation template options.
You would edit your citation to include the pages field and after that, convert the citation to the Author (Year) option, and it now gives you want you want.
How does that work for you? If it does, I attach the modified style and you can copy the text from the appropriate field. in this one to your modified style?
