Hi - is there any way to create a combined report of all Chat sessions requested + all email Incidents created for a given period?   We want to create a summary all "offered" customer volume coming into OSvC for a period, regardless of whether agent accepts or responded.     Seems like a standard way to get a full view of total incoming volume, but we've been unable to combine the tables in a way that will show all chat session IDs and all email Incident IDs created for the period.
