You can automate this; but you have to make sure that the automation you create is going to respect the ratelimits. I'd recommend something simple like using a command alias or short script written for your specific IRC client.
It's what I used to do with that sort of thing; and there are plenty of well known Open Source scripts in the wild as well
As an example; I would use mIRC with it's scripting system and write my own event trigger scripts to automatically request, wait for and then accept the DCC chat requests and route them appropriately in the interface. There were also scripts that helped with getting the lists; unpacking them, and displaying those lists in my client...so I didn't have to extract the text from the zip myself, and could select what I needed from the bot.
All of this was lightweight automation that was intended not to flood the bot with commands and fed into command queueing modules that let the bots have time to process.
Sometimes in those days you could get actually (+b)anned, Auto/KILL'ed or /(G/K):LINE'ed for causing a bot to crash...so you had to be careful and respectful with regard to scripts.
TL;DR; know your bot, source channel & network rules, and write your own scripts for safety or read any scripts you import in carefully and understand what they're doing.
