Save project and or mask

Hi,
Actually, it is not possible to save our work.
The most of time, i work on very hard indoor picture and i need many hours to correct draw a mask and ajust local white balance or brightness.
I think that it will be great if we could save our work or all the masks and reload them after.
Thanks
