Multi Level Select list replication

I hope you can help with this...

MightyResource version of Multi Level Select could add sub levles as so..

Root

--sub root

----sub sub root

instead of using the "Values constructor" param.

is this not possible any more as there are a few Multi Level Select fields i need to copy with the same structure in different Item Types. If not is there a work around as the lists i have to construct are quite extensive.

Also if not could you please give this option in the next update as for some situations this would make things easier.

I hope this makes sense

thanks in advance
