LinguistLyx: label on group of subexamples

[Petr Šimon]

(I am not on the list, please CC)
Hello,
would it be possible to change the subexamples so that a group label
is provided. In fact would it be possible to automatically add a label
for each subexample (just empty label with prefix such as "ex:" ) and
one for the group?
Many thanks
Petr
