Players with feature to add external subtitles?

[roguejp]

I have a problem that there are a lot of UHD's that aren't being released in my country, and are being released in other countries, with no subtitles in Dutch for the kids.

I know that the Oppo has the possibility to add external subtitles when playing a disc, but are there any other 4K players that have such a feature?
I have looked, but couldn't find any, but maybe somebody who actually owns such a player knows.

I made a thread because surely there are other users from other non-native English speaking countries who have the same problem.

Thanks in advance!
