Custom pattern clozes

[talacchi]

Hello,

I am trying to make flashcards where a same card would hide many answers, looking like so:

Option one : [...], then [...]
Option two : ...

which would then show :
Option one : [answer 1], then [answer 2]
Option two : [answer 3]

I've tried follow the tips on this page, but each cloze generates a card, which ends up being quickly overwhelming. How am I supposed to write this for it too appear formatted on my cards?

I use curly braket to generate the clozes. I love the custom pattern {{[123::]answer[::hint]}}, except I already used :: in too many cards to change it. Is there a way to use a custom format like {{[123\\]answer[\\hint]}} for example ?
Can I get an explanation about how to use the 123 ?
Thank you very much !
