Automatically spoof MAC address when interface is brought down

[commentsabout@riseup.net]

Hello,

I am a Debian 8.7 user.
I use the default Network Manager.

I would like to know if there is a way to automatically spoof the MAC 
address of my wireless interface every time I bring down (and up)?

I have a Thinkpad x210 and there is a physical switch for the wifi 
interface. For the time being, every time I close my laptop lid and open 
it up again, I have to manually:

> su
> macchanger -a wlan0
> exit

Is there a way to automate this?

Thank you in advance for your help.
