For inbound service mappings, mostly a cosmetic and organizational thing, there is no current way to group related services or ip addresses associated with them. You have to delete them all and remake them in the ordering in which you would like to see them in the UI. It would be a nice feature to have ALL lists using the same drag and drop ordering that we have available in other lists.
I’ve asked for this before. Seems easy to implement, same functionality as the firewall rules. Nothing new to invent.
