VM Boot Sequence?

I have 3 or 4 VMs I want to run on one machine. Is there a way to set the order in which they start up when the host is turned on? Maybe using a start up delay?

 

Hi, you can start it manually, one-by-one.
Will it work for you?

 

I am starting the VMs automatically when the Mac starts. I understand that I can manually start them in order but I'm looking for a solution that allows me to start them automatically in specific order when the Mac starts.
