Topic: read more in attribute target = "_ top"

Dear:

I still use an old version of cutenews, 1.5.3, because it is reliable and it works for the small site I manage.
I just have a problem that I hope you can help me solve, I would like to press "read more" the link to the news will load on a new page, but with the attribute target = "_ top". Is it possible to achieve that?

Thank you
