Alliance Fleets - only allow certain corps in alliance?

Is this possible?

So if we were looking to have a fleet that was visible to only certain corps in an alliance, how would you suggest we do this?

I’ve tried setting standings and allow fleets this way (set “included” corps to Excellent, “excluded” corps to good at corp contact level), but this then meant that people in my corp couldn’t join the fleet because my corp has no standing with itself!

Hopefully I’m missing something obvious here? Thanks!

Sounds a bit shady. You want to create a secret fleet that your other alliance mates dont know about?
