Edit hitFrame annotation without 3ds max

[BleedingEye]

I've a lot of animation in which the actual hit effect (e.g. unarmed attack) in about 7-8 frames later than the animation so I searched around to find a solution to fix this. Unfortunately most of the detailed tutorials I found require 3ds max with havok content tool. The only version of max I have are 2016 and 2017 for which the HCT is nowhere to be found for these versions.

 

Now I know there are some methods where one can convert the desired animation from .hkx to .xml (using convertUI and such) and edit it that way but I can't "read" it, I can't find the hitFrame annotation which I need. I even compared the .xml files with vanilla ones but still.

 

So my question is, is there a (other) way to edit, insert, remove the hitFrame without using 3ds max and HTC?
