eclipse - How to remove old repository URL from MercurialEclipse plugins repository location field -

I have a mercury repository in which I push my changes using MercurialEclipse plugin using Team -> Push. Now the repository URL has changed, and Eclipse always remembers the old URL in the input field, which has been selected as the default, and I have to make a new selection from the pull down list. There is a very small problem, but there is no less troubled. Is there any way to clean out the old value from this area, so I do not need to take manually manually till the end of time?

Alternatively, how new is the new repository entry to change?

find out that you can change the default by right-clicking on the repository -> Properties -> Mercurial -> Change the default repository also allows the old repository URL to be deleted from the same interface.
