Save a copy, then either drag-copy the formula for each spell till you reach whatever % you desire, or alter the formula that sets the #ticks to be whatever you want to hit. Done.
Not asking why you care about this much haste.. but to reach +200% hasted coa (36 ticks), you would need raid haste, lust, serking, meta proc, affi darksoul and 10899 haste from gear, or just 84k flat haste.
This is realistically only ever going to happen on the pull - it isn't really worth optimising - and if you drop off any of those buffs, the required haste is not really obtainable (>25k).
