Salvaged Materials from TI stored for later use - MRc3 or MRc9?

One suite within a multi-tenant office building is being remodeled as a spec suite - some dividing walls and doors are being knocked out to open up the space. There are 8 large anigre veneered doors that are being salvaged and stored in the building for later use in future TIs. My question is, how do I account for these doors? My take is that we can't count them as salvaged on-site materials since they are not being re-installed in the space (so would not count toward MRc3) but we can count them as materials diverted from landfill in MRc9...does this make sense?
