[Calamath]

I will share with you the special code I use in Calamath's Shortcut Pie Menu add-on.

for index = 1, GetTotalCollectiblesByCategoryType(COLLECTIBLE_CATEGORY_TYPE_COMPANION) do
    local collectibleId = GetCollectibleIdFromType(COLLECTIBLE_CATEGORY_TYPE_COMPANION, index)
    d(collectibleId)
end

good luck.
