Self-mute with loop_mode=one_shot compatible with rgc:audio sfz player

[Buy-One]

Got stumped with this task. What i've unsuccessfully tried so far:

1.

<group> 
loop_mode=one_shot

<region> 
group=1 off_by=1
key=60
sample=mysample.wav

2.

<group> 
loop_mode=one_shot

<region> 
group=1
key=60 volume=-196
sample=mysample.wav

<region> 
off_by=1
key=60
sample=mysample.wav

3.

<group> 
loop_mode=one_shot
key=60 sample=mysample.wav

<region> group=1

<region> off_by=1

4.

<group>
loop_mode=one_shot
group=1 
volume=-196 // with and without
pitch_keycenter=60 
sample=mysample.wav

<region> 

<group>
loop_mode=one_shot
off_by=1
pitch_keycenter=60 
sample=sample=mysample.wav

<region>

The sfz player seems to ignore group number based mute if the target region is mapped to the same key as the one it's supposed to be muted by. It does support group based mute if mute is initiated by a region mapped to a key different from the target region.
off_mode value doesn't affect the result.

Definitive answer from René at the time was along the lines of "you don't want to do this" (kind of Obi Wan Kenobe-style).

sfz.dll explicitly - a chosen behavioural design - will not self-mute on the same note trigger.

Thank you. Kind of a bummer. How were they expecting to tame volume build-up in rolls?
And yet in SFZ v2 it was implemented, either by René or by somebody else.

I kept pestering.
