Caching multiple versions of a modpack

[Audion]

Is there a way to get the launcher to cache multiple version of a particular modpack so you can more easily switch between different versions without needing to re-download the whole pack EVERY time?

copy and move your modpack folder in FTB/ to another location then update.

Actually the Curse Voice Client already has this feature. You can create multiple instances of the same pack and each can be a different version.
