Make Soundpaint Downloader remember a default folder (or shortcuts to your folders)

It seems that when I start Soundpaint, it's nice that it prompts me to download new purchases, BUT... it doesn't seem to remember where I keep all my other Soundpaint libraries.

 

It'd be nice to remember the "default folder" here, or have a button to navigate there directly, so I don't have to find it manually each time.

 

The process is already on the verge of being so simple, this would make it even more directly gratifying!
