Hi Yu, I juse checked, and you can have only one palette at a time, even though you can have multiple metric overlays. When you tweak metric settings, it affects all metric overlays (at least the palette).
There is a way to channel up to three metrics into a RGB map (Attributes: Metric: Convert metric to RGB), but I think you'll have to split your maps into positive and negative that way, so you're not any better off than having two t-maps. The other solution that comes to mind is thresholding one of the t-maps at +/- some threshold and drawing borders around the resulting clusters (something caret_command can automate). The borders can be overlaid on the other t-map. Finally, you can multiply the two t-maps together to find out where they are/aren't on the same page.
