Add audio and subtitles to blu-ray disc

[MovieCollector]

So, this is kind of a sad story, since Disney stop releasing blu-ray's in Portugal and focus only on DVD's, and I wanted to have their movies in high quality.
Then I thought, I can take the audio and subtitles of the DVD release of Portugal, and add it to a foreign blu-ray release, but it looks like no one knows how to do so, can anybody help me? I've been searching how to do this during the whole year, and I can't find any tutorial or program that might help.

Resuming:
I want to extract the Portuguese audio and subtitles from the DVD release of Portugal, and add these in a foreign blu-ray release while keeping the menu, scenes and extras. Thanks
