I propose that we create a button next to the purchase button that is labelled:
"Buy all"

The basic idea behind this is to buy one of each commodity for trade route profit tracking.

It would make things a lot easier..

Any ideas on this, improvements?
Feedback Welcome.

Doesn't Trade Assistant have this?

I'm not sure, I don't have TA ;)

Then get it.

No, TA doesn't have what i suggested.
This is to test sell prices without clicking on each commodity and Hotkeying "p".
To buy one of each and sell it at a particular place. TA only gathers Buy data, and Sell data ONLY WHEN YOU SELL A SPECIFIC COMMODITY TO A SPECIFIC STATION.

will add that to 1.11 then.
