Yes, this can be done, but it will require a lot more memory. Both hosts and referrers have *lots* of unique entries in most logs (whereas requests have much fewer), so it would significantly increase the memory overhead of the processing.
There are lots of existing arguments in this list archive about when such things could or could not be done and whether the option of enabling or disabling such reports could be determined by condiguration rather than design. Right now, the design spec (as far as I know) is to not include any such reports.

Re: Referral Time Reports

or lots of similar questions." [from FAQ]
I feel my suggestion is not analogous with these. In such cases analog would first aggregate entries that belong together (e.g. log lines belonging to the same host or same file) then sort them by another parameter (e.g date or file).
To create a referral time report, analog does not have to aggregate entries that belong together because each referral is on its own. A referrer field is a straightforward, easily recognizable, one-off information, like a page request. I am not a programmer (not by far), but to me it seems that a time report should not need cross-referencing as long as it counts individual, discrete entries, without any pre-aggregation.
Perhaps I am wrong, I only wonder. Thanks for your help.
