OK, that was rather an important piece of information which you really should have given in the original question... without that I wasted effort trying to find the option in the spectre integration. Since Eldo is not from Cadence, we don't own the integration...
Shows the importance of providing all the relevant data when asking questions!
Luckily my spectre-related guesswork proved by luck to be related to a similar option in Eldo. But that was just luck.
