How to configure tiered plan pricing and get broken down reports?

How to configure tiered plan pricing and get broken down reports?

Hi,

I have a product which I price differently based on my customers' revenue.  I was thinking of having 1 product with multiple plans to implement this. However, I don't want the plans to read something like:

Product A
  Subscription Plan (Tier 1) $100
  Subscription Plan (Tier 2) $150
  Subscription Plan (etc...)  $...


I would prefer if they would all simply be called "Subscription Plan". 

This creates a problem with reporting however. You group everything per name, and not per plan code.  I saw no way to add plan code to any report.  The only way I could do reporting like that is to export the data in CSV and then do my own reports, which is a bit annoying giving I would have to manually export many different files (Customers, Subscriptions, Invoices etc.) to get different types of reports. 

1) Did I miss anything? Any idea?
2) Is there any other way to do custom reports with the plan code in them?
     (preferably without coding, but I can do it if necessary)
3) Is there a way to export all files at once?

Thanks!
