Map hostnames dynamically?

Is there any way to map the hostnames of containers dynamically?

I have a bunch of containers called things like:

hello-world----worker1.fidk2md92mz
hello-world----otherworker.md9sdfm2

and I'd love to replace those hostnames in my logs as just worker1 or worker1.fidk (first four characters after period)

Is that possible via logspout?
