How can I change the display setting for Pro Sites Free Members

Hi

How can I control the setting in Pro Sites Management for the below section:

Example:

(Manage Site : My Test Site (Blog ID: 2)
"weasels whacka's blog" has never been a Pro Site.)

Can I change the setting for weasels whacka's blog" has never been a Pro Site to something like:
weasels whacka : Free Member

And if for Silver | Gold or Free Trial Members
their status will display like:
(a) weasels whacka : Gold Member (Free Trail)
(b) weasels whacka : Silver Member

p/s: my question a little bit link to my previous post : https://premium.wpmudev.org/forums/topic/pro-sites-free-users-level-display-error#post-738263, maybe you can get more clearer picture from the screenshot in this post.

Thanks
