WIMP API and desired functions...

Does the WIMP API allow to save favourites inside the WIMP plugin instead of generally in LMS?
Now it is only possible to save a favourite in WIMP by opening the WIMP standalone application and save it there...and the access it inside WIMP on LMS.
Is it also possible to put national (Swedish in my case) new albums and songs into LMS? I only see that in the standalone WIMP, in the LMS plugin there is only general new songs and albums.

If it can be done, please add those features...cheers.
