[Snapshot Pro] What is the best chance to restore sub-site only from whole network backup (snapsho

Hi there,
I had a complete network backup before i make a major changes (Primary Domain Name). However, after completion one of my sub-site have missing theme setting (header, menu..... everything related to customization via theme) is reset to default (or original state).

Any chance i can restore that specified particular sub-site rather than whole network?
