Mercurial: Export last n revision into MQ

is ther开发者_JS百科e an easy way to export last n commits into a new mq queue and strip the commits from the real repository?

I do often start out developing a new feature, later realising I did something wrong/would want to use MQ to fold patches.

I am currently doing:

1. Export last n commits as single patches
2. Strip last n commits
3. create new mq
4. import all patches in reverse order

It's simple (as long as there are no merges):

hg qimport -r base:tip

And voilà.
