You can achieve the result you want with:

	.HM I \" Set Roman for first Level Heading
	.de HX \" rebuild the heading number ommiting level 1 if level > 1
	.if0\\$2-1 .ds }0 \\n(H2.
	.if0\\$2-2 .as }0 \\n(H3
	.if0\\$2-3 .as }0 .\\n(H4
	.if0\\$2-4 .as }0 .\\n(H5
	.if0\\$2-5 .as }0 .\\n(H6
	.if0\\$2-6 .as }0 .\\n(H7
	..
