Aegisub, is there any tag that functions like layers?

[linhoct11]

I'm still new at this.

So I'm trying to add a rectangle opaque box for 2-line subtitles. I found a way to do it, by adding a layer with █'s behind and just change their size. But doing this, I have to add it to every other lines.

Is there any tag like

{\layer1}█████{\layer2}Text here

or something like that?

If not is there a way to put a rectangle opaque box?

Thank you.

Borderstyle 4 is for doing that but not all renderers support it.

Could you please give me an example? I'm not familiar with this.
