In several cases, the antenna pattern depends on operational conditions of the system the antenna is assigned to. For instance, cellular systems apply antennas with pattern dependent on the width of the sector that the antenna shall serve, or for the Fixed Service, the knowledge of the antenna pattern size, frequency is inherent to the workspace that you will simulate. Hence predefined set of pattern may not be adequate, and an antenna plugin that is able to provide the feasibility to generate appropriate pattern for each event would be more suited.
The example below shows an excerpt of the built-in antenna plugin ITU-R F.699 that takes into consideration an equation instead of a preset values.
