50 row limit - Merge and Cluster

50 row limit - Merge and Cluster

I am trying to standardize about 28000 rows.

When I select Merge and Cluster, it limits each run to 50 rows.  This is not practical for many data sets.  I cannot find reference to the limitation in either Zoho subscription or help documents.

How do you apply Cluster and Merge to large data sets?
thanks,
Jeff
