No, we just use "This page intentionally left blank" on every blank page.
However, you could save a text variable (i.e. conrule="\Page \,variable.txt,\blank/\') on the blank page and ALWAYS use it on the recto pages. You could reset the variable to null (i.e. conrule="\\") AFTER the e-i-c that starts the recto page.
That way, if the variable exists, it will show up on the recto page and if it is null, it will still be there, but nothing will be rendered.
