Set chapters manually

I would like to request a feature that the user can define the exact read status.

(example: like title: god slayer I read 10 chapters and the latest chapter is chapter 23) so I can define that I already read 10 chapters rather than no chapter read or read till the latest chapter.

Also, this read status (i.e 10 chapters) should be transferred to the new source if i ever transfer tracking from one manga source to another (transferring from website 1 to website 2 the read status should migrate as well)

https://anilist.co And https://kitsu.io/manga already have this feature and it's a must to a have for any tracking services so please implement this feature. I would love to see it in Kenmei as I am planning to migrate completely to Kenmei.
