Non-Persistent Mode?

Hello, new to Parallels (new to Mac OS in general). In VMWare, I can configure a disk to be persistent/non-persistent. In the latter mode, I can make any changes to the guest OS and once I power it down, the changes are discarded. Is there such a mode in Parallels?

"Nonpersistent
Changes to disks in nonpersistent mode are not saved to the disks, but are lost when the virtual machine is powered off or reset.

Nonpersistent mode is convenient for people who always want to start with a virtual machine in the same state. Example uses include providing known environments for software test and technical support users as well as doing demonstrations of software. Any disk type can be used in nonpersistent mode.

If your virtual disks are in nonpersistent mode, you can take advantage of the repeatable resume feature, which allows you to save the current state of the virtual machine when you suspend it, then resume from the point at which you suspended it every time you start the virtual machine. For more information, see Resuming Virtual Machines Repeatedly from the Same Point.
