Move more than 2bil plat

[Ferd Burfel]

Hi all,
looked all over but can't find solution.
EQ2 limits transfer from bank to character to 2 bil.
I thought darqui let us exceed that limit. Am I wrong?
If so, what are those squares with 2, 5 10 20 etc for? I tried them thinking that would work, but they only picked up 2,5,10, and 20 plat.
Thanks for any clarification.
Same question goes for trading. Can we trade more than 2 bil at a time using Darqui interface?

Thanks again
