Share environments across API definitions

My question:

Just a general question on Environments. I seem to recall in the past the abili5ty to share (or reuse) an environment for multiple API definitions. However, with Postman v9.3.1, it seems that, once I assign an enviroment to a given API, that environment is no longer available for assignment to other APIs.

Am I missing some setting(s) on the environment to allow it to be reused across multiple APIs?

It would be a terrible maintenance situation if I had to replicate the same environment for dozens of API definitions.
