Coming from an Access based system where I could merge(Union) as many queries at once that I wanted to(I had one where I merged 20 different queries at once) , it is very discouraging and time consuming to be restricted to doing two at a time.  Query List isn't an option because it doesn't refresh the records. Merging queries removes duplicate records and this is necessary when combining groups that may fall into various types of criteria.

Please add an option to merge multiple queries at once!!!
