When filtering by a given lineage in cell line selector, there can of course be multiple subtypes that belong to that lineage. For example when filtering by Peripheral Nervous System:
There are 2 subtypes belonging to this lineage: Neuroblastoma and Nerve Sheath Tumor. But if one wants to quickly filter out nerve sheath tumor, they are presented with all subtypes, not just the two existing ones:
Over multiple lists/cell lines/lineages, this becomes a bit of a nuisance. It would be convenient if the only subtypes populated in the subtype filter list were only Neuroblastoma and Nerve Sheath Tumor (in this example), and for the same in the Lineage sub-subtype category.
