Hope I'm explaining this correctly so its clear.

I'm drawing a unit which uses flexible hoses to interconnect filters and creating a general arrangement drawing to list the parts required. The flexible hoses are all identical but follow different paths within the assembly, rightly or wrongly I've created a different part for each hose which follows its individual path but pretty obviously in the BOM it lists them as separate items as they're individual parts/assemblies. is there a way to combine them so it simply lists as needing 12 hoses instead of listing 12 individual parts as single items?
