Is it possible to add somewhere information about ownership of multiple same modules?

For example there is number in "My Modules" section informing how many modules are used in actual rack...

Would it be possible to keep track of how many instances of specific module you own?
Maybe the number could be 3/2 - first number is how many modules I own and second number is how many modules I used in rack.

And just idea, is it possible to track the number of used modules acros the all racks?
