Use objects from pre-introspected schema's without prepending schema name

The title may be a bit vague, but this example will make it clear:

I want to be able to write

'DBMS_OUTPUT.PUT_LINE()'

instead of

'SYS.DBMS_OUTPUT.PUT_LINE()'

Both work, but the former is faster to write and most code examples on the web don't include it. And DataGrip only offers code completion for the latter. So being able to do this will save time.

Is this possible with only changes on the client side (so no creation of aliases etc)?
