Make the Select Company dialog sizable and not a fixed dialog

The Sage 200 company selection dialog presented when a user changes company or logs into Sage 200 is currently a fixed dialog which only allows the display of the first 6 sets of data or companies to be displayed, I have a customer with 172 companies defined and it is tedious to scroll through the list. It would be far easier if this box could be resized if required, as an extra bonus a search filter could be added such as is used in the desktop lists
