Hi @MN_10518175
Unfortunately the menu in the workspace is hardcoded.
It is not supported to change it.
But if you want to do some extra not recommended steps you can check specific class that is responsible for that actions.
This is not supported and not recommended.
!If you do not know what you are doing, don't do it. !
You need to find com.ptc.windchill.uwgm.cadx.ws.WsMenuBarHelper class.
It is located in a wncWeb.jar
You need to recompile it and change it then place it to the standard wch/codebase folder structire and then remove it from wncWeb.jar ...\Windchill\codebase\WEB-INF\lib\wncWeb.jar
In this class you find a definition where the revise action is added
this.addAction(var4, "REVISEITEMSMULTI", "Toolbar_MULTIREVISE_label", var5, this.getImage(var2, "netmarkets/images/revise.gif"));

You can change the condition that action is not shown.
compile the class and place it to the correct package place in codebase/com/ptc/windchill/uwgm/cadx/ws
