Repeat group Hint?

Can a Begin-Repeat group have a Hint added to the presentation of the
repeat group?...........xls2form allows this but does not present the hint
in the survey........

it just says "Would you like to add a Group?" I have tried to add a
dynamic label but the synchronicity of the survey does not validate the
field I am using until after the group is added so that does not
work..........I was trying to do something like this........ but has not
produced the outcome I am looking for..........The hint may solve the
issue........Anybody have any ideas?

type name label relevant calculation begin_group child ${label_name}
textchild_nameEnter the Child's Name calculatelabel_name

if(../child_name='','Enter Child's Name', ../child_name)
