It is common UX to allow selection of multiple objects in one go via mouse and/or keyboard. Usually, by dragging the mouse with or without pressing shift over the desired objects to either select or deselect them. Right now, you have to go one-by-one and click every object you want selected.

Also common is selection of all objects (e.g. by pressing ctl/cmd-A). Exercising some foresight in the context of Capacities, I think it would be useful to be able to select all the objects in the "conceptual view" even if separated by pagination (see image). For example, if I have 67 people that fit a certain filter to which I want to apply a batch modification, it would be useful to select all of them at once, instead of going through 3 pages and repeating the process.
