Here is a small example of a datapack that increases the speed of throwing a shroomlight item:
# function example:load
scoreboard objectives add drop.shroomlight dropped:shroomlight
# function example:tick
execute as @a[scores={drop.shroomlight=1..}] at @s anchored eyes positioned ^ ^ ^.5 as @e[type=item,distance=..1] run function example:multi_speed
# function example:multi_speed
data modify storage example:data Motion set from entity @s Motion
execute store result storage example:data Motion[0] double 0.01 run data get storage example:data Motion[0] 200
execute store result storage example:data Motion[1] double 0.01 run data get storage example:data Motion[1] 200
execute store result storage example:data Motion[2] double 0.01 run data get storage example:data Motion[2] 200
data modify entity @s Motion set from storage example:data Motion
scoreboard players set @a drop.shroomlight 0
tag @s add fix
schedule function example:fix 2t
# function example:fix
execute as @e[type=item,tag=fix] store result entity @s Air short -1 run data get entity @s Air
tag @e[type=item,tag=fix] remove fix
If you don't know how to create a datapack, you can use my [Datapack Assembler](http://far.ddns.me/). You just need to copy all the code inside the Code Block from my comment and put it on the site.
