In 3E, the effect you are looking for is (as in 2E and Scrollmaster's answer) Variable.
Variable: Action: Standard, Range: Personal, Duration: Sustained. 7points/rank.
There is a -1point/rank flaw called 'Slow' which means your power can't be reconfigured during an action scene, only between scenes. It states that the GM will determine the time, but it should be short enough to happen within a game session but long enough to not happen in combat (it also suggests you can spend a Hero Point to reconfigure in a desperate situation).
You might also want to apply the -1point/rank flaw 'Uncontrolled' to the power, meaning that your character doesn't control the allocation of these points. This would mean the GM would decide how they are spent.
So if you, the player, spend the points once (or possibly twice) per story, it's a 6 point/rank power that gives you 5 points/rank to spend during 'downtime' on a new Device/Power/etc.
If the GM spends the points on your behalf and Q hands you a brand new Austin Martin with a bundle of doohickeys that you have no say over, it's 5 points/rank and gives you 5 points/rank of powers. Just be prepared for it to sometimes be a flying car when you're going to end up being teleported to Atlantis (and be ready to spend a Hero Point and some down time to reconfigure it to a submersible car).
As with any power which can be reconfigured during a session, it may be good to have a basic 'set' of things it can do prepared beforehand (for instance, a set of vehicles with their base cost, and how many points they have left over for customizations) so that it doesn't slow down gameplay too much.

It is a bundle of all of the individual items. I just did a spot check from the book and the website. They are all accounted for and there are none extra. The chief advantage to the collected edition is price — it's much cheaper to buy them in bulk — and in the extra sidebars discussing how to handle tricky powers.
Incidentally, it's not a bad question because the Threat Reports did omit one or two entries, I think because they planned on putting those ones into the upcoming Freedom City book.
