Can I list and edit words that have been added to the dictionary (autocorrection) of a document?

I have some names in my document that are labelled as grammar errors. With right click on the word a menu appears with the option Add to Dictionary that when selected all occurrences of that name are no longer labelled as errors.

How can I see a list of all words I’ve added to the dictionary?
How can I edit or remove some of the words I’ve added to the dictionary?
How can I make sure that these words are registered inside the dictionary of the current document and not for all documents?
Would be possible to make a different dictionary that contains only these names?

Lastly. Can I register auto-correction for a name? So when I type it wrong it gets marked for correction.
Thanks in advance, I hope everything is clear.
