seperate folders to scan per library item

[Bhive]

I would like to have the option to scan (in the Add files" menu option) different folders to be added for the different types of the library:
One set (as it is today) for "music"
A possible separate set for "Audiobooks"
Etc.

The reason is that these items are close in nature (audio) but still have a very different use, and are likely to be saved on different HDD locations/ devices.

I tried to define a second library for this purpose, but it's not as friendly.

I think in concept, this has some relation to the suggestion on topic "http://getmusicbee.com/forum/index.php?topic=8685.0"

And thank you for a wonderful product.
The more I use it, the more I love it.
