May Zone Selective Interlocking and both setting groups be utilized at the same time?

On the Sepam 20 series relays the zone selective interlocking (ZSI) or the input swapping of the settings group may be used but not both. When ZSI is selected in the relay setting groups A and B are replaced by the Time-based protection function and the ZSI protection function.
With the Sepam 40 and 80 series relays both may be utilized at the same time.
