Nactation question

Posted By: Igor

I'm wondering how to best include double-take into a Nactation sequence? For example, suppose we have this position:





White is Player 2

score: 0
pip: 163
Unlimited Game
Jacoby
pip: 155
score: 0

Blue is Player 1
XGID=aa-B-BC-A---dE---d-e----B-:0:0:1:00:0:0:1:0:10
Blue on roll, cube action?

If I wanted to stop at the cube decision, then it would be nactated as 52S-33A-F-C (or 54S-33A-F-C). But now suppose blue doubles and white takes, and now blue has, say, 42 to play. How do I include the double-take part into the Nactation sequence to get to the checker play decision?
