I would like to create a new Condition Macro. However, I could not select Condition Macro from Macro Type drop down list.
You can create a new Macro with only Macro Type displayed in Macro Type drop-down list, "Attach Event", "Site-Defined Condition", "Execute Remote Reference" or "Multiple Notification". Other types of Macro that are not displayed in the list, such as "Condition" and "Action", cannot be created, and which is working by design. Please create the macro with the available Macro Types instead of the Condition Macro, or a customization will be required, which is out of our support.
