Can we have comments to comments to comments?

So it would like like this

COMMENT_1
>COMMENT_1_1
>COMMENT_1_2
>>COMMENT_1_2_1
>>>COMMENT_1_2_1_1
>>COMMENT_1_2_2
>COMMENT_1_3
COMMENT_2
COMMENT_3
Rather than it being only comments and comments to comments, so only 2 stage hierarchy - Comment_1 and Comment_1_1 - only 2 levels.
