Adding devices via ZHA - What about a stop button?

Is it just me or are there two basic sequences for adding Zigbee devices via ZHA?

Method 1: Click the Add Device button within ZHA Integration Configuration screen. Then put the device into pairing mode.
Method 2: (Reverse of method 1) Put the device into pairing mode then click Add Device in ZHA Configuration.

Now, I can’t always remember which method to use. If I use method 1 when I should use method 2 then I am left waiting ages for the inclusion process to time out. Is there a way to stop the inclusion process? Do I simply leave the screen?

It would be nice if there was a button to stop the pairing/inclusion process.
