Ability to configure default destination repository for PRs opened from forks

When you have a new forked (current) repo and you create a pull request that pull request is incorrectly pointing to the original repo and not to the current repo.
This is very confusing and it is extremely easy to get it wrong.
There is no way to set the default target repo to be the current forked repo instead of the original repo. (I have searched for a solution and asked the support too... )

1 - the default should be the current repo not the original repo (bug)
2 - you should be able to set the default repo in the settings (enhancement)

In my case, there is NO intention to ever merge the repos back together again.
Dont want to manually have to change this every time in the provided drop down since it is very error prone (easy to forget)
