Move on conveyor as a bundle after multigrip

I am trying to PnP components onto a conveyor as a bundle. Components part of a previous assembly (Assy1) going into another one(Assy2). I want to drop the components off on the conveyor in horizontal orientation - Tried 2 approaches to do this -

  1. Robot program
  2. Adding a frame to the receiving process node on the conveyor to match required orientation

With both of these approaches, the receiving node on the conveyor singulates the components from the bundle and then transports out each part individually. The only way it transports it out as a bundle is if the ProductPositionFrame is not customized and I select null, MainFrame or OutFrame.

Does anyone know why this is happening? And how do I transport out the components on the conveyor in a horizontal orientation as a bundle?
