CanTrade Values to allow stall NOT trading

Yea ... So I recently removed this option for item mall items.

But instead of setting them to be blocked off completely from players that cannot donate.

I want to make them sell-able through stalls only and not trade able.

CanTrade 1 means they can trade through exchange as well as stall them for gold.

Is there another value to Prevent Exchange but allow Stalling for Gold ?

Anyone ?

Bump ... Still looking for this value.
