Can we create local and global variable in the new copilot studio

I've recently gotten access to the new Copilot Studio experience and have been exploring the new Skills-based architecture.

In the previous experience, we could create global and local variables, making it easy to store information during a conversation and reuse it across topics, actions, and conditions.

In the new Copilot Studio, I haven't found an equivalent concept. Is there currently a way to create and manage variables that persist throughout a conversation?

If not, what's the recommended approach to storing information collected during a conversation so it can be reused across multiple Skills, Tools, and Agent Instructions without asking the user for the same information again?

I'd love to hear how others are handling this in the new experience. Any best practices or workarounds would be greatly appreciated!
