Way to count how many times a texture/material/model is being used?

I'm looking for a way to count how many times a particular texture or model is being used in an .esp.

For example, say I have a mod which adds a new building with lots of Preserved Pies inside.

I would like to count how many "\Meshes\Props\FoodandFoodware\PreservedPie01.nif" meshes are placed in the building by the mod.

Similar for textures, like how many walls use "Textures\Architecture\Buildings\MetalSheets01_d.DDS", and so on.

Is there a script for FO4Edit that does this, or a way to do this in the Creation Kit other than going around the entire space and spotting things manually? I'm a novice in both, I tried looking around but couldn't find anything.
