Something like this?

webuse nhanes2f
logit diabetes i.hsizgp  i.black i.female age i.female#c.age, nolog

margins , at(female = 1  age = 40 hsizgp = (1(1)5) )
mat at = r(at)
matnames at
local a = r(c)
foreach l of local a {
	_ms_parse_parts `l'
	local names = "`names' `=r(name)'_`r(level)' "
}
matrix colnames at = `names'
mat list at
svmat at, names(col)
