This very useful request directly relates to the improvement item as listed by @Umut to support individual firewall rules for each Windows Service referenced here: Individual rules for each Windows Service, in the Firewall - #8 by infosec, which also ended high on the priority list by us users that Umut requested. Hope Springs Eternal.
Can you please at least add the PID for the process in the next release, this will help a lot, as there are tens of scvhost instances, the PID will direct the module and it is super easy to add.
