Region lock and playback of DVD ripped to ISO

Initial attempts at getting my DVD collection ripped and playing on Kodi (v17), and having problems.

Used BDloct DVD ISO Master to copy entire region 1 DVD to .iso on NAS drive. In Kodi navigate to it in file view and hit play. Film menu comes up, select play and get a “This disc is not formatted to play in this region” message. If I go to setting and set “Force DVD region” to 1 then it will play.

I had hoped that Kodi would be able to just play all my DVDs (mix of region 1 and region 2 discs) without having to faff with settings every time. Can It? Do I have to do something when I rip? Removing region when ripping still had the same issue.

Maybe I am approaching this the wrong way? Space is not an issue, and I do want to keep the version variations that come with some of the movies, hence looking at ISO instead of mkv. I started out (decades ago!) with a chipped DVD player to avoid region lock, then multi-region support arrived, I am hoping that Kodi can cope seamlessly with this too.

More boradly how best to approach ripping my DVD collection to NAS drive to play via Kodi?
