Okay, so you edit the service directly; same as with Tomcat's provided
tools.

Does this support multiple side-by-side Tomcat-based services?

I have a client who runs our product on Windows (we usually run it on
Linux) and there are 2-4 separate Tomcat-based services on each node,
so they have "Tomcat 8.5.x for FOO", "Tomcat 8.5.x for BAR", etc. in
their service descriptions. Can they use your installer to upgrade
just one of those with a new Tomcat version?
