Covenantal theology simply doesn’t incorporate all of the time detailed in the Bible. That’s why dispensationalism can incorporate “covenants,” but covenantal theology can never comprehensively cover the range of time viewed in the bible.
I guess you are correct if you mean that CT does not invent gaps (ala Daniel 9) and propose regurgitating past prophecies far into the future (ala resurrecting the Roman empire and rebuilding the temple so it can be knocked down, again).
