XL Reporter Norminal Nos. Can I pick Summary Norminal ???

PLease advise

Say we have 5 levels of Nominal

. Level 5 being the lowest level.

In XL Reporter if you want to choose any other level except level 5 should it work?

Nominal No have 10, 11, 12 & 13 , either pick these of put bracket against all of them.

Summarise into Nominal 100 .

That Nominal 100 is level 4 . 10,11, 12, 13 Level 5 ,.

Can I pick that Nominal 100 instead of picking Nominal individually.
