I'm using umbraco 7 and am in the process of making a custom property editor with angular js. One requirement I have for it is that once the user selects a particular string using the editor, it will automatically pass that string as a parameter to a partial view macro to be run in the template. My hope is that all the backoffice user will have to do at that point is insert the Umbraco PageField for the property into the template and the partial view macro would be run with the selected value.

I assume this is possible since the rich text editor property editor appears to be doing this very thing when you use it to insert a macro. Can someone help me with the basic steps involved in accomplishing this?
