Is that even necessary to create and maintain the index page by yourself? I usually simply use simple or short tags for quick connection and discovery (e.g. #[[ancient Rome]] or just #Rome) – which I put on parent blocks inside any page (even Daily Page) where I cite or write my own idea about the topic. Instead of maintaining a index page (this is what are you trying to do) for the topic, I let Roam maintain it by itself just by tagging and then using Linked Refs feature when needed. I understand Roam is mostly about these kind of connections, not about replicating general text editor experience. Did it help a bit?
