Android wireless debugging on multiple devices

By following Google ADB Documentation i am able to coect to device wireless . But i want to coect more than one device.

For adb wireless to work i have to restart adb in tcpip mode

Once i did that i can coect to a device but to coect to another device i will have to restart adb in usb mode again which will discoect the first device.

Simple solution would be to coect both device with usb and then restart adb in tcpip. But i don't have any extra set of usb cable right now.

So is there any other way to coect more than one device except for the method i mentioned above.
