in the older Versions of CA Catalog, where the static table structure was used for designing Service Option Groups and Options it was possible to copy an element to another group. But with the new design this isn't possible anymore.
Also there is no way to export/import a single Service Option to copy the element.
Therefore my wish would be that either, when you copy a element it is not automatically pasted at the end of the group but you have to paste it manually so that it would be possible to switch to another group (maybe different business unit as well). Or implement a possibility to export/import a single Service Option to achieve the same.
