My TRS22PE (build 123801) has
- no "Instant Load" or "InstantLoad" assets built in
- two "Instant Load" driver commands that are "Installed from DLS"
- <kuid2:45324:555017:8> Instant Load Command
- <kuid2:833171:100752:5> TCL Instant Load
- and two more "InstantLoad" driver commands also "Installed from DLS"
- <kuid2:67585:1017:2> InstantLoad
- <kuid2:67585:1022:1> InstantLoadLocos
These four are also the only "InstantLoad" or "Instant Load" driver commands available on the DLS - ignoring those older copies that have been updated - so I cannot see where you get six of them from unless from 3rd party sites or DLC.
Of those the only ones I use are
<kuid2:67585:1017:2> InstantLoad (to load wagons but not locos) and
<kuid2:67585:1022:1> InstantLoadLocos to only load locos (water, coal)
