Multiple Data Types within an Array Element?

Is there a way to have multiple data types (bool, string, float, int) within a single Array Element? I would also want this array to be public so that I may modify variables in the editor.

Here the best example of what end result I'm looking for:

variables I'm working with:

AudioSource audio;
float audioVolume;
bool playOnce;


AudioOptions
Element 0
audio
audioVolume
playOnce
Element 1
audio
audioVolume
playOnce
Element 2
audio
audioVolume
playOnce

 

Make a struct that contains audio, audioVolume, and playOnce, then make an array of those structs.

 

Thank you for the help Garth. I made the struct into an array but it didn't show in the inspector. I found out that I have to use [System.Serializable] right above my struct to get it to work.
