 Hi sickness.

 I'm following zooko's advice, since I have the same problem. My use case
 is described in #1657 if you're interested.
 I've created a [http://pastebin.com/6w8AibEf bash script] that may help
 you. It's not the most efficient way of doing it, but saves me a lot of
 time.
 If some maintainer can upload it to some misc tools folder i the repo,
 maybe others will be able to use it as starting point and hopefully
 improve it, since my bash skills are somewhat limited.

 Hope you find it useful.
