I often get client requests to analyze specific group of employees selected only by their emails. The selection doesn't map to any combination of org dimensions, so it is not possible to select them using regular filters. It would be much helpful, if we could have a query filter based on a series of string values. It could work like the SQL's filtering:
WHERE EmployeeId IN ("ABC","DEF","GHI")
For my current case I need to select 450 employees from a list. Firstly, I query the whole 7k population and then choose my focus group. Not very efficient method, my initial queries are just unnecessarily big.
