No.
Yes, silly wording of the regs. Unless "specifically stated", it is all requirements in category. Especially that 100hrs command..
Some people may upgrade NPPL etc, so wouldt possibly have lots of dual in SEP cat. If they don't do IR, could then count command of tmg or heli towards the 200tt for licence issue.
No way around. Unless doing CPL in other country system like FAA and knocking off command time using such licence.
