How to store information into arrays ? (via Enum)

I have an array of static meshes. How do i combine it to an Enumeration so that I can store information into the singular meshes ?

Example:

My Enum: 1,2,3,4
Set static mesh1 a “My Enum” value of 2

I’m probably not explaining myself very well but i’m not even sure that this is possible so … If you could correct me that would be ace !
