How fun is it when you realize that you have to add a property to 20 different page types?
Been there done that. So today when I realized that I had to do it again I wrote an admin plugin instead.
With this plugin you can create a new property just like you do in EPiServer, and then you select wich PageTypes the property should be saved to.
If a Property with the same name already exists it will leave the old one.
This Plugin has only been tested with EPiServer CMS R2, but I think it’ll work with any CMS5 releases.
If you are interested in a plugin like this to EPiServer 4, then you should check out PageTypeUtil on EPiCode.
