Summary field on inventory-page

We often use the inventorypage (myobservium.com/inventory/) to find number of specific linecards or chassis or other parts for which this inventory is very helpful as all devices gets autodiscovered in to Observium.
However when the list is quite long we usually have to copy-paste it to excel or something to be able to count how many entities we found.

It would be very useful if the inventory page showed total entites matched at the bottom of the table to fast find how many of parts where found.
