How does caqe extract the assignment of the first quantifier block after bloqqer preprocessing?

Hi, I'm working on an encoding that requires me to 1) find the satisfiability of a QBF, 2) find the assignment of the outermost existential block when the formula is SAT. I observe that the combination of bloqqer and caqe is the most efficient. However, bloqqer preprocessing will eliminate some variables in the outermost quantifier block which makes finding the partial assignment very difficult. I tried the --partial-assignment=1 option in bloqqer, but it seems like even with that flag set to 1, some variables in the outermost quantifier block are still eliminated.
I think caqe has a --preprocessor=bloqqer --qdo option, but it does not work if I build caqe normally. It says bloqqer cannot be activated. May I ask how does caqe extract the assignment of the outermost quantifier block of the original QBF after bloqqer preprocessing? Or is there a way to activate the --preprocessor=bloqqer --qdo option?

Thanks.
