How to enable Dynamic Lock in Windows 10 Creators Update to lock device by phone

Dynamic Lock is a new security feature starting with the recently-released Windows 10 Insider Preview build 15031. It is based on the Bluetooth signal, and user must sign-in to Windows with a password. Once you step away with paired phone, Windows 10 Creators Update will wait about 30 seconds and then automatically lock your Surface Pro tablet or Windows PC in your absence.

How to enable Dynamic Lock in Windows 10 Creators Update to lock device by phone
Before using Dynamic Lock feature, you need to pair at least one Bluetooth device, such as your smartphone, a wearable device (Fitbit or others). Even You can have multiple phones paired with your Windows 10 PC, and all of them are working for that.
* Make sure all paired device have turned on the Bluetooth function.
* Within the Settings app, navigate to the Devices > Bluetooth.
* Select the phone from list, click Pair option, and then click Yes to confirm the passcode matches.
However, I couldn’t select the related devices by the method, because the Setting app crashes. Then I had to pair them successfully through the Bluetooth control panel.
After the Bluetooth-paired phone is connected, go to setup the Dynamic Lock.
* From your desktop, tap or click on the Start button, and click on the gear icon to open the Settings app.
* Go to Accounts, and select Sign-in Options in the left side.
* On the right pane, check the “Allow Windows to detect when you’re away and automatically lock the device.”box to turn on Dynamic Lock. That’s all.

Now the default 30-second delay can not be changed and I would like to absolutely have the option to choose which device is used for Dynamic Lock.
