Show Cue System

Ver 11.7.1.3 (x64)
Having been alerted to issues with copying cues containing level change sub-cues in an earlier version 11.6.xx, I downloaded version 11.7.1.3 to test.
So I created a file (attached) like the following

Q1 Emergency Vehicle
<1> Audio file with all outputs -inf
<2> Level change cue to Q1 <1>
<3> Level change cue to Q1 <1> after end of prev sub cue
<4> Level change cue to Q1 <1> after end of prev sub cue

etc. when I copy Q1 as a whole and create Q2 I get:

Q2 Emergency Vehicle
<1> Audio file with all outputs -inf
<2> Level change cue to Q1 <1>
<3> Level change cue to Q1 <1> after end of prev sub cue
<4> Level change cue to Q1 <1> after end of prev sub cue

I was hoping that the sub cues in Q2 might point to the audio file in Q2

Q2 Emergency Vehicle
<1> Audio file with all outputs -inf
<2> Level change cue to Q2 <1>
<3> Level change cue to Q2 <1> after end of prev sub cue
<4> Level change cue to Q2 <1> after end of prev sub cue

ie When copying a cue
If sub cues refer to sub cues within the same cue we are copying
THEN point them to the same sub cues in the new cue
ELSE copy them verbatim from the source cue

Does that make sense, or have I missed something?
