API Question

I am going to be writing a script that will be integrating with the virtualmin API to create sub-servers of a site, and it will use a proxy website to the sub-server's parent site. I already have everything in place for the setup to work properly, but since this script will be running on a cron nightly to create these sites, I don't want it to stop / start apache with the creation of each site. I would prefer to create all the sites, add the proxy website to each site, and then do the final apache stop / start at the end of creating all the sites. As there could be multiple sites being created, it would not make sense to have it do all that restarting with each sites, it would make more sense to do it at the end. Is there currently a way to accomplish this?
