it's getting a bit annoying having to continually do that

Asuming that you are using Rig Manager, make sure you know what is selected and you are saving :
So a PROFILER needs to be connected, in Performance Mode, and the destination Performance needs to show at the PROFILER display as well as be marked with a headphones icon in the Rig Manager Performance list. This limitation makes sure, that you can hear what you assemble and the Rig you paste is always in focus of the Editor. Consequntly storing the edited Performance is consistently performed via the Store buttons at the bottom of the Editor.
Selecting the Performance (single click) is not sufficient. You need to load it (double click). "Loaded" is where the headphones icon sits.
Selection is sufficient to move items or edit tags. Changes become immediately permanent as soon as Enter is pressed. Even multiple items can be selected.
Loading allows only one item at a time. This is what the Editor is referring to. If you edit e.g. increase Gain the corresponding line in the list changes color from green to red. The same applies if you paste a Rig into a Slot of a loaded Performance. Here explicit storing is required to make modifications stick - like in the hardware. This mode of operation refects loading, editing, and storing of the hardware.
Both, selection and loading can coesist. You can select Performance 3,4,and 5 and copy and paste these into the Local Libary or change their names in one go, while Performance 17 is loaded. Keep that in mind. There is a value in having both modes. However, in this scenario you can only copy & paste or drag & drop Rigs into the Slots of Performance 17.
Perhaps it helps to compare Rig Manager selection via single click to typical file manager operations on a PC: moving single or multiple objects, copy & paste, changing file names or file attributes. Dropping, pasting or pressing Enter makes such changes immediately permanent.
But in order to change the content of a Word-file you need to load it in Word. Normally, an explicit store is required at the end to make edits stick. Without storing edits get withdrawn. This is how the PROFILER hardware works. You load one object at a time, edit and then store or leave without storing. And the Editor with its Store buttons at the bottom reflects this approach loading single objects via double click.
