Edit the templates of xhld*_*.html.
(I recommend to use tplsadmin)

Quote:Use xhld itself multiply. (not cloing block but cloning module)
Thus, you can distinguish the templates of xhld0_*.html, xhld1_*.html ...

Or you can try to modify the theme assigning id for each blocks.
Thus, you can also apply styles for each blocks using the id.
