Multiple data selection and deletion

Sometimes, wrong data might be reported because of some changes of the tracked website. Because this affects the max and min of the graphs and so the scaling in the 1 week / 1 month time frame, the wrong data must be deleted so you can have again a normilized graph. But there is no option to choose multiple data, only delete one by one and confirm the deletion dialog every time. It could save a lot of time especially if you have short refresh periods like ex. 1 hours, and you might end deleting 48 wron data entry points in a 2 day timframe.

I believe it shouls be a simple implementation but a very important one!
