Which RPM Spec Macro provides OS Minor in Release, eg el8_4?

How do I get the OS Minor in the Release field of the RPMs? I understand that the spec file entry %{?dist} expands to the OS Major

Name:     mypkg
    Version:  2.3
    Release:  1.2%{?dist}
    Arch:     noarch

and so the package is

mypkg-2.3-1.2.el8.noarch

Which marco could I use so it also provides the OS Minor, eg

mypkg-2.3-1.2.el8_4.noarch

thanks
