Hi,
I will look into this. For now if you want to create a Guide Channel go to Guide Channels in Edit Guides, click Add and create a Per-Root Channel, use the Paint Brush in Edit Guides to paint the roots, then you can select this channel in the Assign Guides Channel Dialog. To paint vertices a long the hair is the same process but create a Per-Vertex channel instead of a Per-Root channel.
