How to insert a vent on the top of the first vessel (with a goose neck) of two stacked vessels? - AutoPIPE Vessel

Greetings all,

I'm new to Autopipe and I cannot model a nozzle on the top head of a vessel that has a stacked vessel above it. The two vessels have a shell separating them, and I would like to include both a vent for the first one and a drain for the second, both nozzles would have a goose neck comming out of the shell placed between them.

Does anyone knows if this is even possible?

Thanks so much in advance for taking the time given!
