How to get toolbox components all together in BOM from different sub-assemblies

Hi,

I have sub-assemblies with same toolbox components as other sub-assemblies and I want to show the total quantity of all toolbox in the BOM( I think that's the correct name).

I have too toolbox components in the toplevel

Is it possible to do? If yes, how?

In the image attached you can see number 15.4 is the same bolt as number 25 but 15.4 is from a sub-assemblie.

Thanks,

Manel C.C.
