async trading default currency

Can we please select which one is the default trade currency in async trade?
currently is chaos.
It has happened to me that after i change it to divines, if i do a character swap, it default back to chaos after logging back in, and you dont notice, after posting something, I realise I'm seliing div worth items for chaos, plus the 5 minutes lock doesn't help the situation.
If divines where the defaul or whatever we choose we could skip this problem.
thank you!
