You are correct in the assumption that neither rrdtool nor rrdcached plugins
create LAST RRAs for you. There has been some discussion to improve these
plugins' configurability, and you're most welcome to +1 this. As a
workaround, you can either create the rrds on your own, or use some contrib
scripts in rrdtool dist to add the RRAs tou your existing files.

however, the best would probably be to patch collectd (it's an easy fix).

Cheers
