Tagging parent tags when tagging subtags?

[Constanza]

Basically what the title says; say I have a tag tree that looks something like this
-Family
----Siblings
--------Brothers
--------Sisters
----Parents
--------Mom
--------Dad

If you tag a picture as, say, "brothers", it is only tagged as "brothers", and not as "brothers", "siblings" and "family" (which would, in my opinion, be the logical thing to have); you have to tag them manually for each of the parent categories. Is there any way to make XnView tag the parent tag when you tag its children?

you have 'automatically apply parent keywords'
