COPY_PASTE for Commandblocks and chat

as "commander" i am doing a lot of big commands....

and on java i have a helpful "tool" named copy and paste

now i wanna make a command chain for an nice cam ride....

this are 2 "easy and short" command from bedrock i am using....

/scoreboard players add @[tag=InCam] CamTransitionTimer 1
/camera @s set minecraft:free ease 3 in_out_sine pos ~ 150 ~-150 rot 45 45 

This is ONE java command....

/execute as @a[level=10,tag=10rewarded,gamemode=survival,scores={Money=..999}] at @s positioned ^ ^ ^2 facing entity @s eyes if dimension minecraft:overworld run function reward_system/levels/10/start.mcfunction

good luck tiping that without an commandsuggestion in commandblock  and without copa paste function in chat and command block (WITHOUT ERRORS PLS)

Mojang dont want me to type that out.... so its clearly an missing feature... or in other words BUG
