When using hover text in minecraft, is there a way to keep each entity connected and displayed separately nbt?

Question

I am using a datapack and creating a command, but after getting all the entities with @e in tellraw, I want to display the nbt of each entity. In this case I am trying to use the CustomName of that entity. Among the things I have tried are.

"Chat: entityA (hovertext: TEST.A ) "

"Chat: entityB (hovertext: TEST.B ) "

or

"Chat: entityA, entityB (hovertext: TEST.A TEST B )"

and they are displayed together. My ideal would be

"Chat: entityA(hovertext: TEST.A), entityB(hovertext: TEST.B), entityC(hovertext: TEST.C), ..."

Starting from a marker with tag "main", I want the hover text to display the name of that marker and the name of an additional marker with tag "sub" that is near the marker with tag "main". What is not done here is that I want to execute the same process as above for multiple markers.

Since the number of entities is unspecified, I would like to use @e as much as possible to shorten it. Any other suggestions would be appreciated.

Here is the command

/execute at @e[tag=main,type=marker] run tellraw @a {"nbt":"CustomName","entity":"@e[tag=main,type=marker]","interpret":true,"hoverEvent":{"action":"show_text","contents":{"nbt":"CustomName","entity":"@e[tag=sub,type=marker,distance=..1]","interpret":true}}}

The execution location is the location of tag:main. sub's marker is spawned in the same location as main's.

Version is 1.19.2.

You might be able to do some string concatenation trickery to get to your ideal result, but the easiest one to achieve would be

"Chat: entityA (hovertext: TEST.A ) "
"Chat: entityB (hovertext: TEST.B ) "

The command you're using is already close to achieving that, but it needs a few adjustments.

First of all, we'll want to execute both as and at the main markers. That way we can access them using @s and the location is also changed to their position.

execute as @e[type=marker,tag=main] at @s ...

now onto the tellraw command. For the first set of NBT, we can refer to @s, as that is the marker entity we just selected in the execute.

{"nbt":"CustomName","entity":"@s", ... }

now comes the hover text, where we want to make sure we select the one sub marker that is closest to the executing main marker.

{"nbt":"CustomName","entity":"@e[type=marker,tag=sub,limit=1,sort=nearest,distance=..1]"}

So all in all the full command should look like this:

execute as @e[type=marker,tag=main] at @s run tellraw @a {"nbt":"CustomName","entity":"@s","hoverEvent":{"action":"show_text","contents":[{"nbt":"CustomName","entity":"@e[type=marker,tag=sub,sort=nearest,limit=1,distance=..1]"}]}}
