[Auto start a mod pack when i start the launcher]

I've been playing in this one modpack (Affinity Wars) and it takes forever to load (265 mods) and i have everything setup so its ready for me when i get home from school (boot up pc, start launcher) but i cant figure out how to have it so it will auto load the pack and be ready for me when i get home. Is there like a batch/vbs thing i can do, or some java arguments (im a super skrub with java so pls just have what i need to put in) to make it auto launch the pack.
