how to delete photos ?

deleting photos would be a big advantage in some projects. it is mainly about deleting photos that are not yet part of the alignment or a component. especially if you create components for large projects and upload a wrong photo batch and stupidly save the project. the whole work of setting control points seems to be lost then—and that can really cost time. the passive alignment time is more likely to be accepted than the manual work. so yes it definitely makes sense to be able to remove photos from the project. or am i missing some sneaky and simple workaround?
