Just like you can select multiple days in dayview by clicking before making a booking it would be nice to be able to select a workorder and afterwards the different resources by clicking.
This team can change day by day so working with groups or crews isn't a good option.

In the ideal world these bookings would be linked (for example with a locksymbol) so if you change it one resource it changes all of them.
If you don't want that to happen you can unlock the booking on the chosen resource and change just the one bookingtime.
