Thor,
I'd use the converter Filename - Tag with a formatstring like
%album%\%temp%\%dummy%
After importing the tags I'd create a new action Format value and choose ALBUM as field using
%album% - %temp%
as formatstring.
To get rid of the TEMP tag field, I'd select all files and use the extended tag dialog via View, Tags ....
Best regards,
