All mode jitter setting

I’ve been experimenting with a Shark OpenSPOT 2, which has a global de-jitter setting. The manual mentions changing the setting is primarily for use with a mobile phone hotspot or MiFi. The suggested setting is 1000 (mS?) for use with 3G or 4G.
On D-Star the Shark used with a phone hotspot hasn’t suffered from broken speech, whereas the Pi-Star and an MMDVM board has had quite a few gaps at times. Obviously due to the nature of a 3G/4G connection it’s hard to test with 100% certainty.
With Pi-Star, there is a jitter setting for DMR, but not for other modes. On DMR the speech seems to be fine when connected via a mobile phone connection and a jitter setting of 1000.
Having a global setting would be very useful.
