Ex Usenext user here

Hi guys after another price hike and DL cut I've left Usenext after nearly 6 years.... ( and realised how much I've been overpaying )
Over the last couple of days I have managed to find my way around finding how most things work.....
I have just a couple of questions....
1. I have a set of groups in Usenext that are my go to groups.... can I import a file that lists them or do I need to add them individually...
2. is there a way of finding a file name other than just the hash no from the search... ( liking the search by the way ) but occasionally I would like to browse !!
Thanks in advance for your help....
