Very useful final addition to the multi edit/delete function.
Typically a user will search for certain criteria, and then select
them all to be removed/edited. For example, if yesterdays sets were all
10x150kg deadlifts, but you review your form video and decide the form
sucked, you would want to mass edit them to lower the weight/reps (or
maybe delete them). This way you won't have these invalid entries
ruining all your progress graphs (showing false progress).
