VEGAS Pro 14 Edit Steam Edition

Using MKV files on Vegas
Hi guys, I'm wondering if there any "easy way" to use .MKV files on Vegas.
I know it isn't a file to edit, and I know the solution is to convert every file that I have but I wonder if there is any other way to do it without converting the file.

Plus: My Vegas isn't reconizing .AVI files, anyone having the same problem?
