Double Bass default range

As a double bassist I am finding that the default range for the instrument samples (the white highlighted notes) is a little limited. Whilst it extends down to a low C as the lowest orchestral note with an C extension, it then only extends upwards to an octave G on the top G string . Quite often we double bassists go above that G even in the standard orchestral repertoire. Specifically at the moment I am composing msuic for double bass solo and so Id like to go much higher than the G by a further octave ....well into the upper thumb position upper registers of the instrument

I don't know where the round robin recorded samples stop but wondering if it possible to increase the default range of the instrument on the keyboard input to include the area in the pink?
