Re-target project (aptuse) release (1.0-b2.1) to the correct series

I registered a release 1.0-b2.1 (https://launchpad.net/aptuse/trunk/1.0-b2.1) on the trunk of the Aptuse project (https://launchpad.net/aptuse). Since this is a part of the 1.0 series, I would like to re-target the release to the 1.0 series.

In "link" terms, kindly make:
https://launchpad.net/aptuse/trunk/1.0-b2.1
... point to ...
https://launchpad.net/aptuse/1.0/1.0-b2.1

Eg. of a correct release: https://launchpad.net/aptuse/1.0/1.0-b2

Thanks.

PS: If it is not possible to re-target the release, please delete the problem release 1.0-b2.1 (https://launchpad.net/aptuse/trunk/1.0-b2.1) so I can re-register it properly.
