It's under chapter 16, “The Legislative Process”. I think it's on page 767, under “Clauses Allowed to Stand”:
The committee may, by motion, decide to stand a clause, or a group of consecutive clauses en bloc. Debate on a motion to postpone consideration of a clause is limited to the issue of postponement, and may not touch upon the merits of the bill or of the clause in question. Unless provision to the contrary is made in the motion, clauses which were allowed to stand are considered after all the other clauses of the bill have been disposed of.
