Possible to check if player have DLC access?

[SnowmanDK]

I wonder if there is a function I missed that can tell me if a player have access to a specific DLC.
I need it to hide/show certain quests.

Lets say each DLC was given a number value, like this:
1 = Imperial City
2 = Orsinium
3 = Thieves Guild
and the function was like this:
isDLCAvailable(DLC number)
Returns true/false depending on if the player has access to that DLC.

Then I could do something like this:

If isDLCAvailable(2) then
-- show quests in the Orsinium dlc zone and subzones
end
