Customize eg [more work] buitton text in portfolio?

Hi,
I am setting up a site with creativity template and news show pro.
Loving it so far
I run into the following limitation:
In news show pro (with module mode Portfolio) a button is displayed that says 'more work'.
I know I can change the text to something else via a language override, but this is actually to limiting.
I want to use multiple portfolios: eg. more art, more pictures, more paintings, etc.

This is currently not possible (correct?)
It could be fixed by setting up an extra variable [button name] in the config part (above the variable where you specify the url) or, it could be handled the way image show is making this possible by adding '[the name of the button]' in front of the url...

It can be done by hacking NSP module and adding new functionality. Beside that I can't help much more.
