Feature request - Variable sharing

I would like to be able to pull from variables that are available to create custom reports. 

Example, currently I can only see lot expiration date on the Lot Expiry report. I would like to be able to view my whole inventory snapshot at a glance and would like to be able to pull quantity on hand, allocated, on PO, and expiration dates of my inventory and currently that is only possible if I pull the Lot Expiry and the Product Stock Level reports and find a way to combine them in Excel. This creates errors, costs a lot of time. If I were able to pull the variable of “allocated" and “on order” to the Lot Expiry report I wouldn't need to do this. Allowing the cross-use of variables would be very beneficial to our business.
