'Tutorial' as Sub-type for Journal articles

I have some journal articles that comes into the category of tuorial. Eg: http://onlinelibrary.wiley.com/doi/10.1002/(SICI)1096-9888(199904)34:4<244::AID-JMS775>3.0.CO;2-0/abstract
These articles are categorized as ‘miscellaneous’ by paperpile. I think they should be categorized as ‘journal articles’, perhaps under sub-type ‘Tutorial’.

It should definitely be filed as a journal article. We will look into this issue.
