[Weidu noob] Can this be done in Weidu and maybe code?

Hi everyone! Been playing BGEE game (and all before, BG1, BG2, BGtutu) and I've messed with Near Infinity (took forever) so next time, I'd like to Weidu it!!! So, here's what I want to do!

Situation: Price of everything in my game is about 150% (rough time) and as I added items so that money is hard to come by... So I though of adding treasures (low gen) to all empty chests/crates/etc... To make it less grindy...

In BGEE, there are random item generators (RNDTRE01/etc) and I'd added then (took forever in NI) to each and every empty container... Next time, I want to Weidu it (lot faster). So, what I wanna do:

Weidu checks each and every ARE file... In those file, he checks if they have containers... If the containers are empty, it puts RNDTRE01 or RNDTRE02 in them (maybe a 50/50 chance?), then saves...

Can it be done? (By the way, I can "tweak" Weidu coding but I can't really code it... I mean, I'm like a weidu noob as stated in the title!)

Thanks for reading! If any questions (things you don't understand in my "unclear" message) just reply!

Thanks!!!
