Writer - how to share spelling ignore-all list

I want spell check to ignore words that are particular to a set of related documents without adding the words to the global dictionary.

How can I do this?

As I ask this question I wonder if perhaps I can add them to the template? That seems a bit laborious though. I want to ad the word at the current document and have it included in all the other documents in the set?

The solution that works for me is to create a subject-specific dictionary:language settings/writing aids.

When there is a spelling error on a word I want to ‘ignore’ for this set of documents I can add that to that dictionary using right click on the marked word.
