Is it possible to add another Overworld?

I've been trying to figure out a way to add another Overworld with no luck, I'm stuck to two maps.

Is it possible to add a second Overworld without messing with the first?

I guess you can say I am new to Zelda Classic, but I've tried looking up this topic and got no result, but I do see talk of people saying "First Overworld," ect.

Hi.
An 'overworld' is just another map in ZC. You can add as many maps as you want to.

What specifically is the problem you are having with setting up a second overworld?

Oh, I had trouble figuring out what to do to add another map. Thanks! I found it.
