Adding custom captchas manually

Is there a way to add custom image captcha types manually to GSA CB? Nothing special, e.g. something like this:

I see there is SDK, so I make an assumption there is. How many correct captchas are needed to get CB to correctly solve it?

    hmm that captcha has two big problems:
    a) the chars are with borders, thats solvable but reduces success rate a bit
    b) the bigger problem is the joined chars. That makes it hard to seperate them and perform ocr on it.

    You can try sending me a lot solved captchas of this type and i do my best adding support for it (right answer in file name), but I can not really guarantee a good success rate here.
