Yes, you can create a copier with one copy from (master) account and many send to (slave) accounts easily with out copier configurator. This is one of our most frequently used features.
To copy from one master (copy from) to many slaves (send to) you first go to the trade copier page, under configurator in the navigation menu. Once there, press the add copier button in the top left and create one copier with the master (copy from) and one of your slaves (send to). Once the copier has been create you can then append more and more slaves (send to) accounts to that copier by pressing the add copier button on the right side of the established copier, as seen below in the screenshot.
