Blocking popup when executing a microflow as datasource

I could use some creative solutions for blocking content when running a datasource microflow, any ideas? The situation I've got a page with a template grid and a listen-to for the details of the selected grid item. These details require some objects that need to be unique and are generated when opening that grid option for the first time. I want to prevent users clicking anywhere when this microflow is running. Unfortunately, a blocking popup is not a default option when using a microflow as data source. I've got some ideas that get pretty complex and require some more modelling. Perhaps there's some script or setting I'm not thinking of?

Maybe the dataview loader widget from the appstore could be used?
