combine Macrium image backup with file-based backup to NAS drive?

Hello folks,
I am backing up my W10 machine to a Synology NAS via smb. I can use Macrium Reflect to make an image backup, fine.
I can also use Windows file history to make backups of various directories too, fine. But I do have some complaints about this, and hopefully you guys have some good solutions.
One is that it is kind of redundant and wastes space because most of the largest files are getting backed up twice. Yes, I could technically use image backups only but a) it takes a lot longer than a file / folder based backup, and b) then I need to fire up Macrium on whatever other computer needs to grab this file and mount the image. I like how with the file history I can just go to the smb share and find the file right away via windows explorer.
One big drawback of the file history is that there are lots of useful files all over the place, like in the Program Files directory, or wherever your web browser decides to store the bookmarks file. I can't be bothered to remember to add every single one of these locations to the backup folders list.

In short, is there some good way to do image backups, but have incremental backups that are actually fast, and the files on the NAS be easily readable by another computer without Macrium already installed?
Thanks
