Selling items directly from stash to vendor

I need to ask to GGG if this is a bug or if you gonna implement it in the core game XD?


I already reported it at bug reference number: 3.837.656.958
ScreenShoot:

I found someone that explain how to do it:

I try to check if i can do something more.

I can let and put items without touch the stash (being in the hideout):


I can't do the before in map or other instances:




Can we use it for do chaos recipe meantime?

You can trade directly from stash too:
But only the maximum stackable currency in one normal inventary slot will be transfered. I check it with the shitty currency:
1. I transfer many armourer when the trader have only 1 slot available, he only get 40.


2. I transfer 21 blacks when the trader have 2 slot available, he only get 20

,

What is the point of fixing it?

I think it is a bug for not having an official way of doing this!
