We already show trunnions at elbows in the StressISO with its length. Since these supports are not components in AutoPIPE they can only be shown as the restraint they represents in the ISO. If you want you could model the trunnion as a cross, this way the supporting members would show up. OPIM does not handle structural members.
See WIKI here for modeling a trunnion attachment in AutoPIPE. As mentioned a trunnon modeled with Beam elements will not appear on a stress iso. This has been logged as a new enhancement (1042361).
