Restrict question deletion when answers exist

[yoshi-yyy]

I'm using Apache Answer and would like to prevent question authors from deleting their questions if there are existing answers.
Is there a way to configure this behavior, either through admin settings or available plugins?

When some conditions are met, the user cannot delete it by himself
