Feature Request: Get all NBT data from mob

I'm really looking for some sort plugin that has a code block that can get all nbt data from a mob and save it to a string. I specifically mean the data that can be gotten from the command /data get entity @e[entity specifications] | or similarly to the f3 + i shortcut that saves all of the serverside entity data (but without the /summon part of it).

If we can somehow get a plugin that has a feature like this, making systems that can capture mobs will finally be possible, because all the nbt data can be saved to a string, and then that string can be recalled in a /summon command, allowing for a copy of the mob to be made.
