SOLVED Possible to "mirror" a Sequence?

Hey all,

I've been experimenting a bit with using Sequences as an alternative to stuff like importing from stuff like Spine or Spriter, I thought it'd be cool to be able to build that sort of thing right there in GMS. Obviously this has some limitations since there's no skeletal features (right?) but the thing I was really hoping to see is a mirror option or ability to "flip" the sequence, like using sprite_xscale to flip a sprite around..

Walking to the right works, but to the left.. not so great. :)

I've been up and down in the manual and haven't seen this kind of function anywhere. Does it really not exist?

Never mind, turns out it was a simple enough operation for even a guy like me to get into the struct and flip things around. There's probably more I could do here but this did what I wanted:

if (_facing == -1)
            var seqStruct = layer_sequence_get_instance(sequence);
            var trackCount = array_length(seqStruct.activeTracks);

            for (var i = 0; i < trackCount; i++)
                seqStruct.activeTracks[i].scalex *= -1;
                seqStruct.activeTracks[i].posx *= -1;
                seqStruct.activeTracks[i].rotation *= -1;
