As per my understandin You will have to create separate Machine tempalte for each system. Because it will create different machine keys for your system. Also you can refer the below for more clarity.
@Jon_Smith is correct. Templates are intended to be used by 1 or more machines (ideally each of the machines are setup the same way so there are not any issues with a Processes requiring a specific machine to run successfully).
Please see the documentation for full details on Machines and the differences between a Standard Machine and Machine Template.
