brackets inside other brackets?

[gamer2key]

It would be extremely helpful for me to make prompts like this:

{opt1{opt1.1|opt1.2}|opt2{opt2.1|opt2.2}}

Unfortunately putting brackets inside other brackets doesn't work with the default settings, is there any way to make it work? That would be very helpful

What's the intent of a prompt like that? Nested brackets should work fine by default, provided the rest of the syntax is right...

Simply add more variations in a batch, probably though there are better ways that I ignore.
I just tried again and it actually works, probably the error was caused by the rest of the syntax, stupid me, I apologize for the trouble thank you!
