"Ceiling values may not be changed..."

OK, I'll give that a try as I've got a nice bottle of booze in the cupboard to give me strength.

I assume that in order to do this I'll have to name the rooms according to the American list provided by the software drop down list and not what I would actually call them as a UK resident, bring up the plan for the ground floor, go to the Room Default Settings and change them then bring up the plan for the first floor, do the same again and then once the defaults have been set go to each room and manually change them to what I would prefer them to be.
