mIRC is not a mass file trading program (which is what I assume you're doing using words such as "bots" and "packs" in the same sentence). I see little reason why it should further facilitate users who do not wish to use it for it's actual purpose.
I'm sure there are a number of 'XDCC' or 'FServe' scripts out there that would help you achieve whatever you want.
