Redirect setting to overrule path-alias

Hi,
Following issue:http://drupal.org/node/479890 it is not possible now to use a already available alias as from case for the redirect.
Would it be possible to have a setting and with this setting "overrule alias" then the code will before making the url-redirect delete the alias in the alias table?

Right now I have to
1) build the node
2) set the alias in the node building
3) delete the alias from the alias table
4) then I am able to use the same alias as a redirect.

This is a time consuming process better to have option to overrule alias with redirect and then the step 3 is automatically handled.
Is my future request clear please?

thanks for considering building this!
greetings,
Martijn
