Editing fanned fade-timings in a cue bug

Hello,
I think a customer from us found a bug.
He wants to update the fanned fade-timing for the intensity without opening the Cue Editor.
I tried different command line syntax without success.

101 THRU 110 @ FULL
TIME 1 THRU 10 THRU 1 ENTER
UPDATE CUE 1
-doesn’t work-

101 THRU 110 @ FULL
TIME 1 THRU 10 THRU 1 ENTER
RECORD CUE 1
-doesn’t work-

101 THRU 110 @ FULL
Time only Palette
UPDATE CUE 1
-doesn’t work-

101 THRU 110 @ FULL
Time only Palette
RECORD CUE 1
-doesn’t work-

LIST 1 CUE 1 INTENSITY TIME 1 THRU 10 THRU 1 ENTER
-change the intensity fade time to 1s-

The same when I try this with delay timings.
