Not as far as I know, but it's easy to program. Here's one solution:

preserve
collapse (mean) *
tempfile means
save `means'
restore
append using `means'

The above assumes that all variables are numeric. If they're not, you could replace:
collapse (mean) *
with:
ds, has(type numeric)
collapse (mean) `r(varlist)'
