When macros are used in a page template it would be really cool if we were able to use refer to placeholder values within a macro configuration.
1. The page we want to create contains a Google Map macro and we would like to configure it in a way that the string we collect with the address placeholder is automatically configured as the search input in the macro.
2. We ask in the blueprint for a username and the page template contains the content responsibility macro where this username should be put in.
