How can I move custom panels content from a panel to a mini panel (using Features)? I have created a large number of new custom content pieces with a rather complicated configuration for visibility settings, etc.

However, I now need to re-use this custom content across a large number of panels (originally, I had thought I would only need it for one panel).  So, I want to move the custom content to a mini-panel.

Is there a way to move this content from the panel to the mini panel instead of re-creating it manually?  I am managing deployment through the Features module, so all of my panels and mini panels are already in code.  However, I opened up myfeature.pages_default.inc and there is a huge amount of code; I wasn't able to find the positioning information for the panels/mini-panels.
I ended up just doing it manually.  Though it took some time, I was unable to find a faster solution.
