Dropbox and iCloud Sync

So, I know it's been asked before, but the thread seemed to go nowhere.

I want to sync Dropbox and iCloud together. Why? Because I have ONE single piece of software that I use for writing that ONLY syncs with Dropbox across platforms, but ALL my other writing files are in Word or Pages and live in a specifically organized file setup on my iCloud Drive.

I don't want to lose that setup or move my writing to Dropbox because one developer can't be bothered to figure out how to sync appropriately with iCloud. It bugs me to no end that they have created this amazing piece of writing software that can work across the Apple Ecosystem, but can't figure out how to make sync work with iCloud. It utterly ruins my entire file system if I have to move ALL my projects from their specified folders to Dropbox just to sync them to my iPad, Mac, and iPhone.

Any help would be greatly appreciated, but I suspect advice will be along the lines of "Create an alias."

Thanks!
