Hi rodeus, welcome to Feng Office Forums.
Regarding the specific feature, if you both dig up a bit in the forum, you will notice someone has already developed it.
You should also take into account that the values given to certain developments take the scope of it into account, which sometimes may be quite bigger than the final user thinks it is. It also takes into consideration all the development time and testing it takes, and the possibility that it may crash other features, as well as the time the Feng Office developers have to spare for customized developments.
Best regards,
Francisco
