Easy browsing merchant window?

[Matek]

Hi there.
I have an idea that during your merchant mode (before/after selling),
clicking the item that is in your selling/to be sold list would display a list of current selling price in the broker window.

e.g. Clicking on a Fulginate cluster in my sell list and the broker window will automatically display all current sells price of Fulginate Clusters of my country.

It is kinda hard to explain but do you think it is possible? Enabling this function would help a lot while deciding sale price.

What do you think of it? And since I do not have the skill to make one, anyone who is willing to make one could do so.

Thanks!
