Can we set meaningful merchant tab labels so other players can easily browse interesting items?

When a prospective buyer comes to your merchant, how does he browse for other interesting items you have for sale? It is up to the seller to label his tabs so they will be browsed. Assuming we can still set the ~b/o 20c label to price all the items in the tab the same, it only tells the price, not what's in there. Could we as a seller add more information to it? For example:

Swords ~b/o 20c
lvl21 gems ~b/o 200c
Base staffs ~b/o 20e

PS: One point about scamming - Regardless about my suggestion, if we can set the label to ~b/o 10c, then every item would have to sell for 10c in it. Currently in premium tab you can set the label to ~b/o 10c, but still set a different price for any specific item. If this feature carries to the merchant tabs, a scammer can with the label misinform the buyer about the price about the items he's browsing, but set a different currency as the price to a particular item, for example 10d for a Ming's Heart, to make players do hasty buying decisions.
