Is it possible to use regular expressions to search across continuation lines in Code References?

I've had occasion before where I've wanted to look through multiple-line SELECT statements -- looking for instance for instances where I selected from a particular table.

I know how to do this if it's all on the same line ... select.*from mytable ... seems satisfactory.

So, is there anything that could be placed in the regular expression so that it would know to search continuation lines?

Thanks in advance
