is it possible to have a build from https://kojihub.stream.centos.org/koji/ having subpackages that are not going to be shipped in main CentOS Stream repos being somehow filtered to ship those subpackages into a SIG repo?

I'm asking specifically about qemu-kvm sub packages we'd like to have in CentOS AutoSD SIG but that are not going to be shipped in main CentOS Stream repos as not relevant/supported in RHEL (qemu-kvm-ui-dbus, BZ# 2207940).

I would like to avoid having to rebuild the same qemu-kvm build within the SIG each time a new release lands in CentOS Stream just to get a subpackage.
