Is it possible to add an import from XML option for Policies and Organization ?

When we are doing installation for our clients a lot of time is wasted just for creating groups, subgroups, copying policies, assigning policies.
It's not hard but it's dumb to click everything, especially because SEPM is not to responsive (honestly it's quite slow interface).

I know I can prepare policies on another SEPM and export them but those are in some proprietary format and I can't correct. But wouldn't it be simpler when it is XML (or any other human-readable format).

This way we won't need to spend that much time at clients site just clicking around and we don't need powerfull laptops with VMs and SEPM installed just to prepare everything for the clients.
It would also help when traveling you can prepare all files on the run and then import them after installation.

I hope I am understandable ;)
