what is the preferred method to move software from the installed products list to unmanaged

Using Client Management Suite 7.1 sp2.   I have a few software what were put on the "installed products" list  which we thought we were going to managed but decided not to in the end.

What is the preferred/best method to move them from installed products to the unmanaged list?

right clicking on the software allows me only  a few options:

Delete / Resource Manager / etc.  None of which really provides a clear direction to move the software.   Your guidance is much appreciated.

thanks
