More intuitive default definition query naming

[wayfaringrob]

When creating new definition queries, do away with the 'Query 1,' 'Query 2,' etc. default naming. It is not helpful; I'd rather just have the SQL string or a portion of it as the default name so I can at least differentiate in the dropdown on the Data tab without having to come up with unique names for all of them.

This is a little more helpful than 'Query 1':

See here for the idea related to expanding the size of that dropdown.
