Downgrading modpacks?

[drag0n2ooth230]

I'm not sure how you guys run everything in this area but with the recent bugs and things with some of the packs, could a downgrading feature be implemented.
In my case I updated to the latest version of minecrack (v7) and then afterwords found out about the server bug for minecrack so now I'm not able to play on the server because i have a later version.
Again not sure if this is possible or if this would even be a part of the agreements you guys have with the mod devs.
Thanks for the consideration and great work!!!!

Its already implemented, click edit modpack and then the most right tab to change versions of the pack
