Method #2 is straight forward (is the one I used the first time), but it has some inconveniences:
- You have to use the name of other dictionary and substitute it.
- You lost the other dictionary.
- When you update through wifi, you lost your new dictionary, that it is substituted by the original one.
Method #1 is more complicated but it is the "definitive" solution. You can add the number of additional dictionaries you want and they do not disappear with the updates. It is the one I have now and I am pretty happy with it.
Note: Do not forget to make a backup of the database, just in case ...
