Is there a way to use joinby with frames? I can of course manage without, but it would be elegant to be able to write something of the form:

Code:
frame create children
frame change children
import children.csv
do child_clean.do

frame create parents
frame change parents
import parents.csv 
do parent_clean.do

frame copy parents family
frame change family
frjoinby familyid, frame(children)
frget age, frame(children)
I can see that frget in this case would potentially be a little more complicated than frlink, but not prohibitively so.
