Is it possible to have multiline info box?

[guoweis-work]

I'm using the syntax like this

<!-- Macro: :box:(.+):(.*):(.+):
     Template: ac:box
     Icon: true
     Name: ${1}
     Title: ${2}
     Body: ${3} -->

Is there a way to enable multi-line info box?

ideally, i'm hoping the markdown syntax would work inside the infobox, like bolding, or bullet points... etc.

I'd love to fix this if you could provide some code pointer.

This works fine.

<!-- Macro: :box:([^:]+):([^:]*):([^:][\s\S]*?):
     Template: ac:box
     Icon: true
     Name: ${1}
     Title: ${2}
     Body: ${3} -->

:box:info::This is Info.
**bold**:

Bolding worked inside the box, but other markdown syntaxes(like bullet points, and code block...etc) did not work.
