Simple animations adjustment

[UserXz]

Hello,
I've found Live Action mod and decided to configure DAR for myself.
So, I want to use some animations, provided by mods.

Some animations are not aligned, and I want to make very simple edit on them: translate and rotate.
I'm no animator, but I think that it should be simple - just apply translation and rotation to some animation entry point.

I've found hkxPoser, tool is great, but I didn't find a way to rotate/translate whole scene, there are some nodes, named LOC rotate LOC translate but I don't see any result when modifing them.
there is kinda center node NPC COM, but if modification is applied to it - it can mess up other nodes movement which alters whole animation.

than I've found tutorials on editing animation the hard way - plenty of tools to import animation in blender. But, here on ll, I've found some posts that such an edit may lead to issues (and actually it is - animation imported according guides has weird movements, scales and so on.)

so my question is, is there not so painfull way to make simple adjustments to animation?

precise example:
I want to add sitting animation to DAR from poser mod GSPoses named GS87.
it need just simple rotation and slight translation.
I failed to do it in hkxposer
when trying to import (convert to kf) it failed with XPMSE skeleton (i guess) with error about bones amount "Error processing skeleton 'NPC Root [Root]' number of tracks exceed bones."
using XPMS skeleton by some suggestion found here leads to wierd animation behavior when playing it in blender. in same topic there is a comment, that one should use only original skeleton.

Thank you

I can't answer your main question but I figured I'd throw this little hint in here in case it is relevant. If the sitting animation is off by about 45 degrees, that is actually caused by the animation played before the sitting animation ie. the one where the character sits down.
