Clustered subsets in ZINC15?

On the ZINC12 site there are clustered versions of subsets, for example the 'Leads Now' subset can be represented at the 90% Tanimoto cutoff level by 322,638 structures:

However, I couldn't find the ability to download clustered subsets in ZINC15. Is it available? Thanks.
