Comment date not available as arguments

Node creation dates (and parts of it such as year, month, day, monthwithyear ...) can be used as arguments in Views, so I can create a beautiful view (I can't say how much I love this module :-) that will give me something like this:

posts --> list of all the posts
posts/dates ---> list of all years with posts
posts/dates/2009 ---> display all the post in a year (and an attachment letting me choose months of that year with posts)
posts/dates/2009/01 --> display all the posts in that month (and an attachment letting me choose days of that month with posts)
posts/dates/2009/01/12 --> display all the posts in that day

What I cannot get is the same with comments (i.e., lists of comments by date):

comments/dates/[YYYY]/[MM]/[DD]

The key thing is dates of creation (in its diverse forms) are not available as arguments for comments, so there is no way you can split comments by date.

I think that would be very useful, but wanted to know OPPs opinion. I am no coder, so I cannot foresee how hard or easy to implement this would be. However, the same is implemented for nodes already, so I hope that is at least a base.

Thanks!
