Alexander Tilanus's dashboard

hi, we work with more than one offices with several bookings agents, would it be possible to add a column 'created by' in the bookings list that appears on the left in the bookings window. And to add 'created by' to the search filter. This would make it easier for the admin and bookings manager to sift through the bookings. And one step further...: it would help me when each bookings manager (we have one on each office) would only be able to see and edit the bookings of 'his/her' bookings staff.......
