xEdit Script or Available Option

[falloutanimation]

Hello,

I am trying to find a way to speed up the below process with either a script or an inbuilt option within xEdit.

I start with an esm and then deep copy override a cell from this esm into an esp.

This esp will now contain a cell with persistent and temporary records that are filled with statics, scol, activators etc etc.

Now, as well as deep copy overriding the cell into the esp, I also deep copy every activator, static, scol into the esp. 

My esp now has the cell record, as well as the records of the activators, statics, scols, etc.

Now, want I want to achieve is, I want every activator, static, scol, light etc that ISN'T within the copied cell to be removed from the main activator, scol, ligh records because I do not need every single one to be in the esp, I only need the ones that are being used by the cell.

I'm not having much luck looking for an answer, 

Does anyone have any insight as to how this might be possible?

I don't want to delete each one manually or add them manually as both take a long time,

Thanks!
