Yes, you can reset it at any time. On each receipt of an initialpose
message, amcl will generate a new particle cloud by sampling from a
Gaussian distribution with the given mean (pose) and covariance.

It's not built in anywhere, but it would be simple enough to write a
little node that takes in the raw scans, adds noise (of whatever kind
you think is realistic) and re-publishes them. If you do that, please
share your code; it would be helpful for others!
