You could create a .local version of your choice of action file and add a
network mask suffix to the address being banned in the actionban= line.
Like "<ip>/24" instead of just "<ip>". This depends on the actionban
command tolerating that syntax, of course, so you might need to adjust
other parts of the action file.
