I wish to list files to play in the PlayLog action in Studio.

What is this related to RingCentral platform or services?

This is a question regarding the PlayLog Action in the RingCentral Contact Center Studio tool.

I wish to play more than one custom audio file. Similar to how you can stack files in the Play action.

So this is a user question rather than a developer question. Let me move it to the User community.

It is a developer question. Studio development. I'm thinking there might be a Java/Snippet solution to my question.

Man, then ask as a developer question with background and details of what you do. Such a vague question will never get an answer.
