Add API/flags to import richer history files

[Alives]

I have over a decade of shell logs with timestamp, user, cwd recorded. I wanted to import all these as well (and not with the same timestamp and cwd). I ended up writing a script to directly add them to the db, but would have preferred if the tool could accept a flag or env var to custom set the parameters for each command entry instead of just setting them to whatever the local and current environment dictated.

Add some ability to custom set CWD, Timestamp, User and the ability to import commands one by one?
