Try "Joviex's Addon Settings Transfer", it's on minion..

You could manually add the SavedVariables file of the addons.
The data is stored on your harddrive at c:\users\windows user name\documents\Elder Scrolls Online\live\SavedVariables

!!!YOU NEED TO LOGOUT BEFORE OR THE FILE WILL BE OVERWRITTEN IF YOU LOGOUT!!!


If the addon name is let's say "Destinations" then there should be a file called Destinations.lua

Make a backup and edit it with a text editor.

There is a structure in there like this:

AddOns_SavedVariables =
{
["Default"] =
{
["@AccountName"] =
{
["CharacterName"] =
{
[data] = value,
[data1] = value1,
...
},
}
}
}

Create a new entry [$AccountWide] at the level of the CharacterName:

AddOns_SavedVariables =
{
["Default"] =
{
["@AccountName"] =
{
["$AccountWide"] =
{
},
}
}

Copy the stuff between the { } of the CharacterName, e.g.
[data] = value
[data1] = value1
...

between the {} of the [$AccountWide] entry.
Should look like this afterwards:

AddOns_SavedVariables =
{
["Default"] =
{
["@AccountName"] =
{
["CharacterName"] =
{
[data] = value,
[data1] = value1,
...
},
["$AccountWide"] =
[data] = value
[data1] = value1
...
{
}
}
}

Be sure there is an , after the closing } of the CharacterName surrounding { }, !

Login and tets if the settings are available for every character then.
If not, the addon is not supporting account wide settings, or you made a mistake and should rollback your backuped SavedVariables file!
