wouldn't it make more sense to add your proxy sources of scrapebox in SER? As I used the proxy scraper of GSA I copied them into scrapebox with good results.
Generaly you are right. But i have good (and paid) public proxys from some supplier. Once a day I am checking them by SB for anonymity and then i send them to GSA, so i wolud like to just paste them.
You can do that when using some other URL for testing that would e.g. show a special word if the proxy is anonymous. Rest is than tagged as not working.

low priority: you could also add anonymity as one of the filter in GSA proxy checker
