CJA datasets - allow ability to force lowercase all or certain fields

Description - For all datasets, allow the ability to force lowercase all or certain fields.

Why is this feature important to you - Currently, if the casing in matching keys doesn't match exactly, enhancement data from lookup and profile datasets isn't available in CJA.

How would you like the feature to work - A toggle to force lowercase all fields in a dataset.  Checkboxes to force lowercase certain fields

Current Behavior - Attributes can be forced lowercase once ingested via data view component settings.  However, this isn't possible before setting matching keys for lookup/profile datasets.
