No verifications when a user is a sponsor of a project - by: bioN

Hello,
I'm using ProjeQtor V7.0.9 and when i deleted some users who are also ressources affected to a project as Sponsor, it seams that they're no verification on that status if they didn't enter real work on that project.
Is there a way to have a warning when deleting a ressource that is part of a project like "you're about to delete a sponsor from a project"

Thanks for helping
