Any way we could get currency 1889 added by default? I don't see a way to add custom currencies.

https://www.wowhead.com/currency=1889/adventure-campaign-progress
/script print(C_CurrencyInfo.GetCurrencyInfo(1889).quantity)

I was able to get this working by adding

if index == GetCurrencyListSize()+1 then return index, C_CurrencyInfo.GetCurrencyInfo(1889) end
at line 137 of CurrencyFrame.lua

not sure if there is a cleaner way to add this as i've never really looked at the adibags code before.
