Is there any way to apply a template for this parameter to every table at once, instead of having to edit the properties for each one? It would be great if there were to be a button to propagate properties, linke the one in Table Properties, or the one in Sequences Properties. Btw, there should also be one in Views Properties....

You can use search functionality to filter objects and then can use "set common properties" functionality (it's Properties button there) to set what you want. Unfortunately properties related to "Using index" are not exposed to that functionality..
Fixed for next release.
