One container many users

I’m very new to working with Shinyproxy and multiple containers, so please tolerate my ignorance. It seems to me that each time a user connects Shinyproxy starts a new container. Is this true? Is it possible to have a single container serving multiple users? In an ordinary workflow, my R application initialises by loading relatively big amount of data shared by numerous Shiny UI users on a single host. Running a single container per user is very prohibitive in terms of memory and time.
