Similar to the other commands which you can issue against (special class) of resources the operations console now offers a new option in the pop-up menu of a resource, which you open with a right-click.
You are able to select "Set Availability Target" fpr End-to-End ServerGroups - the menu entry will only show up when you select any e2e ServerGroup. The entry is not available for any other resource or SA z/OS servergroups.
In the appearing pop-up dialog you can specify the new target value and an optional comment which is only written to the LOG of the e2e automation domain.
The dialog below even shows what happens, if you do not use the spinner (the up/down arrows) to increase/decrease the new Target Value - but you specify a incorrect value (in this case the letter "a"). An error box will immediately force you to correct this mistake.
