Add range selection (shift + click) to List views; at minimum, on Customers -> List

It is currently possible to multi-select customers from the Customers -> List screen by checking the boxes. Selecting the entire view is easy with the "select all" box in the top left.

It is frustrating to select smaller groups of customers, like 10 of them, then skip 5, and then select 20 more; this requires a lot of clicking of individual boxes and takes a long time.

I suggest adding a "hold shift while clicking" feature to allow a "range select." Check first box to select a customer; hold shift and click the final customer, and all of them between would also be checked/selected. This same functionality would be welcome on any screen with a List that has a "mass Actions" feature.
