Conditional delay

Hi all, how would you approach this model?  Workers are transporters and must be present at the servers to supervise each step.  For now I have one worker and am using a personal edition of Simio.  Server1 is an observation microscope where entities pass through a survey step.  Server2 is a robot dispensing glue that has a finite window of appropriate elasticity after mixing.  I started my model with a version very similar to the MoveableOperator where my worker goes back and forth between two servers running 6 entities individually before switching... six being the number of entities we believe can be processed with one batch of glue.  When trying to model the delay step of glue mixing (ideally with worker movement to a separate node or location) I thought to add it as the first in a task sequence at Server2 with the condition that it only need to be applied when the server buffer was full of the 6 entities.  This seemed to not fit well with the priority decisions that the worker already had for movement and the worker stalled.  Basically, how would you model the fact that every 90 minutes we need a 15 minute delay for glue mixing and that once the glue is mixed the priority needs to be at Server2 until glue elasticity runs out?

Other questions:

What expression would tell the worker to ALWAYS transport two entities?

I want my workers to finish all server runs before going on lunch break or end of shift.  Entities will never be unattended nor will workers be interrupted to restart server time later.  What's a good solution for that?
