the "deken" cmdline utility has such a feature: $ deken install -r requirementsfile.txt
however, most people will not have the deken-cmdline utility readily available, so you may find it it of limited use.
is that command line available in all OSs including windows?
apart from, that there's the deken repository where you can file feature requests, and look for/comment on older ones such as [84].
i don't think it is too complicated to add such a feature to the deken-plugin (in principle), but it has to be well thought-thru (as the comment by peter has shown).
