Looking through the MILESTONES, they offer selection of "bonus SQC" at 40K, 60K, 80K, 100K and 120K. etc. These can be applied to the current year as you try to earn and maximize SQC. Are they stackable? Essentially could we select them each time (2,500 SQC) and earn 12,500 SQC to aid in our goal to maintain SE. That's not half bad as this lessens the "SQD" factor from $31,250 (125,000 SQC / 4) a bit.
