Is there any way I can delete a portion of a comment?

The title explains the help I need.

I have requested an edit. But if that is not forthcoming I would like to edit not remove.

Only the commenters can edit their comments (up to 30 mins. after placing them).

Would you guys consider giving the page owner/wizard the ability to edit comments (indefinitely)? The reason being

1. Chazes need, and

2. if someone spams my article with a link to a site but they wrote a compelling and well thought out (specific not general spam bs) post I'd like to be able to keep the post but remove the link or url in it. Seems a waste to have to throw the baby out with the bathwater where a good post is and the link I don't want in there... My current way of preserving that comment is to create a guest comment section and put it there, but that's work...

and

3. So I can edit grammar mistakes and spelling so my page stays cleaner to the bots scanning the pages content (comments count as page content)

Nope, don't agree with this.

I would would not want a comment of mine I left on someones page (not necessarily on Wizzley.com) changed after I have left one. I would see that as being totally rude and would have nothing to do with the spirit of what I wrote.

While I agree with the wish to be able to edit comments, I also agree with the indignation I would feel if someone edited a comment I wrote. I would also be negatively inclined to participate on that writer's pages after that.

It would open the door to abuse. Some authors would change all their comments into glowing reviews of their articles.  

Makes sense, didn't think of that... (good points Kangaroo and Sheri as well)
