I've realised I would like the confidence intervals also. But I'mnot sure I can find the right values in -ereturn list- that willallow me to calculate the CIs. Can anyone help?

If nothing else you could generate variables equal to those values, cut your data set down to one case, and save under a new name. Something like sysuse auto proportion rep78 , over(foreign) matrix bmat = e(b) forval j = 1/10 { gen prop`j' = bmat[1,`j'] } sum prop*
