If you use the ispconfig dns mirroring functions as described in the multiserver tutorials, then you dont have to add a slave recird at all as ispconfig takes care for mirroring the record to the dns slave automatically.
As far as I can see, it is still missing in 3.0.5, but don't worry, it is a bunch of lines of code and I have added them into (my local version) 3.0.5 (that ones I coded into 188.8.131.52)
