Scalability of Digital Assitant

Content

Hi,
We were getting familiar with Digital Assistant and found few doubts ?
we would appreciate your assistance in understanding them well,

1> Can we add other custom questions, other than given out of the box questions ?

2> And also what if we dont want some of given out of the box questions ?

3> And while using channels, is it necessary to get logged into the instance first ?

Thanks,
Satya
