Change MLE estimation regression output

[Dustin Weaver]

Hello all, we're using a MLE estimation that produces a regression output like this using the command "estout using estout_test.txt, cells(b) replace"

.
b
prob_1
appeal_back_spine .0220817
increase_back_spine .7360941
reopen_back_spine .1118292
multi_back_spine .0641385
_cons -.8408572
prob_2
appeal_cardio -.1796807
reopen_cardio -.0070915
_cons -.9704458
prob_3
appeal_ed -.205206
reopen_ed .0114364
_cons -.5317771

What I want is an output like this:

prob_1, appeal, .0220817
prob_1, increase, .7360941
prob_1, reopen, .1118292
prob_1, multi, .0641385
prob_1, _cons, -.8408572
prob_2, appeal, -.1796807
prob_2, reopen, -.0070915
prob_2, _cons, -.9704458
prob_3, appeal, -.205206
prob_2, reopen, .0114364
prob_3, _cons, -.5317771

Any ideas?
