Is it possible to power the Grand Central with 5V....but not

Adafruit documentation for the marvelous, wonderful, absolutely incredible Grand Central (yes, I like this board!) states (https://learn.adafruit.com/adafruit-gra ... al/pinouts) that

There are two primary ways to power the Grand Central:

-- Through the Micro USB port up at the top left
-- Through the DC jack at the bottom left

and goes on to observe that with the DC jack one should

Provide about 6V-12V here to power the Metro.

Is there a way to power the Grand Central with 5V NOT using the Micro USB port?

I'm using the M4 in the context of some outboard electronics that will draw about 1.5A at 5V, which means that I can't pull this through the board. Therefore, I've devised a power distribution circuit for that bit, but I hate to need a dual voltage power supply to bring 6-12v to the DC jack.

My questions are thus

-- can I power the Grand Central via the DC jack with 5v?
-- if not, is there a way I could safely bring 5v into the board other than the two primary ways listed in the aforemetioned pinout documentation?

I suppose I could stuff it in via the USB port, but I'd prefer to leave that port unused for when I need to attach this device to another computer, rather than using it just for power.

Thanks!
