Use the data-* attribute to embed custom data

Is there a way I can assign extra/other data params to movieclips like we can do with html a tags - https://www.w3schools.com/tags/att_global_data.asp

I have.a bunch of movie clip icons where I need to assign each a group of values I can access in an onclick function. For now I just need to do a javasctip alert and show the values when an icon is clicked. For example, I'd like to add something like data-name="Thunderbird", data-level="Expert", data-link="https://mylink.com".
