One-to-many and conditional execution of random commands

[XiaooHu2002]

I would like to make a suggestion, I don't know if I have not understood the wiki.
The advice is: for example, I have three landmarks (city, work, home).
I want to make the script block to implement three locations randomly teleport (for example: /warp city), but I can't seem to find the method on the wiki. I saw on the wiki that the method does have the ability to input multiple instructions in a single /sdb command. But it can't make each landmark have probability and randomly teleport. My understanding is that one-to-one teleport, and it can't implement one-to-many conditional teleport.
My idea is that a script box has the following three instructions
/warp city (probability: 30%) , /warp work (probability: 20%) (temporary permissions: work) ,/warp home (probability: 50%)
And can be according to whether there is temporary permission to send, if not, can randomly send the remaining two landmarks, there is temporary permission, can send three landmarks
I don't know if the author can understand the meaning.
If this plugin can implement this method, can you please tell me the author.
