Is there any way to retrieve the logit transformed confidence intervals as displayed by -svy: tabulate- when using estpost?

e.g.  -estpost svy: tabulate var1 var2, proportion cv ci obs col format(%11.0g)-

I can obtain most of the output I want using the following, however the confidence intervals are untransformed:
- estout using output.txt, cells("b se ci_l ci_u") unstack-

I'm also not able to extract the coefficient of variation but can calculate it easily enough using the standard error.  Transforming the confidence intervals manually seems impractical due to differences when compared to the values Stata calculates, perhaps due to the accumulation of rounding and the challenge of inputting the t critical value based on df.

This is a "nice to have" because I could use the untransformed ci's, it's just not ideal.  I've perused Statalist and the reference docs for estpost and estout but haven't come across a way to do this.
