"Query used" defaults

Hi all,

Running AX 2012 R3 CU9.

When running confirmations, pick lists, etc - is it possible to change the values within "Query used" defaults?

I'm aware you can save the values in a selection as a separate query but that's reliant on usage data not being deleted, and as far as I know you can't make a custom query the default.

Presumably it must be getting the data for the default ranges from somewhere, is there a way we can slip in a few extra fields in the default "Query used" selection without breaking base classes?

Thanks very much in advance,

Luke
