You can create your own custom actions by extending Alfresco programatically. This is done in two parts: Extending the repository with your action (Java code), and extending the Alfresco Web Client to show your action and collect the necessary parameters for it (Java/JSP code).You should check out the abstract class:org.alfresco.repo.action.executer.ActionExecuterAbstractBase.java
That class implements the action interface and takes care of most of the boilerplate functionality leaving you with two methods to implement: The first is the one that specifies the parameters you need to perform your action; and the second is the action implementation itself.The best way to go about this is to look at an easy action, like:org.alfresco.repo.action.executer.MoveActionExecuter.java
And leverage most of the code.As for the Web Client side, look at this file for inspiration:web-client/source/web/jsp/wizard/create-action/actionmove.jsp
Best of luck.–Sumer
