I have the same question as a new user with a complete collection of US since 1930 When adding stamps in bulk, can you apply a filter so only the major Scott number stamps without sub varieties are shown and selectable in the catalog? I mean, for example, that only Scott 4352 is shown, not Scott 4352a, 4352b, 4532c. etc. as well. That way I could enter a few thousand at a time for initial entry and fine tune things later if wanted. Otherwise the range select option is of limited use as most people aren't going to have every sub variety of a stamp. Thanks
