Dynamic @Track variabes

Hello, I was wondering if there was a solution to this?  

level1Disabled
level2Disabled
level3Disabled
level4Disabled

If I had variables in aura I could set the value like this........

component.set("v.level" + number + "Disabled", true);

How can I do the same think in a Lightning Web Component?  The values are @track (ed).....

@track level1Disabled;
@track level2Disabled;
@track level3Disabled;
@track level4Disabled;

this.level1Disabled = true;

I want to do something like........

this."level" + number + "Disabled" = true

In JavaScript, you use the "index" notation, just like for an array, except it's a string that you use. We can also use the template literal to make it look a bit easier to read. You can do this: 
this[`level${number}Disabled`] = true;
