Add possibility to write on line 2 "Amount:" (and add alias to translate in other languages) and on line 3 add alias for "B" and "V"

Is your feature request related to a problem? Please describe.

Can you make this works? and also if its possible add alias to custumize in config file "Sell" "Buy" and "Amount" as a translation proposal

Describe the solution you'd like

In the forums here in Brazil I saw many customized chestshops that instead of using B 1:1 S to buy and sell, they used C 1:1 V of "comprar" and "vender"(the translation in portuguese), if it were possible to create alternatives that would be amazing

Describe alternatives you've considered

also i used essentials to change the lines with "/sign" command and works very well, this is a very useful feature for moderators that can be implemented
