NPC Parameter keys

[Chaos ruler]

Is it possible to use 2 times a "Module_shop" for a selling and buying part?

like for example:

ye well first of all the <Greet, farewell, idletimeout, walkaway, alreadyfocused, placedinqueue>
That's not the point but this.

<parameter key="module_shop"  value="1" />
<parameter key="message_buy"  value="blabla." />
<parameter key="message_onbuy"  value="blabla." />
<parameter key="message_needmoremoney"  value="blabla." />
<parameter key="message_decline"  value="maybe you will buy it another time." />
<parameter key="module_shop"  value="2" />
<parameter key="message_sell"  value="blabla." />
<parameter key="message_onsell"  value="blabla." />
<parameter key="message_nothaveitem"  value="blabla." />
<parameter key="message_decline"  value="maybe next time." />

What I like to have is:

BUY
When you say
Player: Buy ITEMNAME.
npc: Do you want to buy ITEMNAME?
Player: no
npc: maybe you will buy it another time. <----------

SELL
When you say
Player: Sell 20 ITEMNAME.
npc: Do you want to sell ITEMNAME for blabla?
Player: no
npc: maybe next time. <------------------

Otherwise I will have no clue!

EDIT: Or should I make more parameters?
