Is It Possible To Add Startpage?

A number of months ago I switched from Google to Startpage for my Web searches. The reason? Unlike Google, Startpage does not associate my IP address with my searches nor does it keep logs of all my Web searches. And unlike similar Privacy-centric Web searchers such as DuckDuckGo, Startpage uses Google to obtain its results.

I’d like to know if it is possible to use Startpage as my default Web searcher in DEVONagent, DEVONsphere Express and DEVONagent Express?

It should be possible to create a plug-in for DEVONagent Pro and to create your own search sets using this plug-in but it’s not possible to modify DEVONagent Express & DEVONsphere Express.
