I wanted to use a none global ground symbol. There isn’t one and no way of creating one or creating labels with symbols in general. One way to do it might be to have a special footprint.
Some ways to it:
I use different ground symbols for different isolated grounds. All of them are global, but I know where I use them.
Or as you point out, a non-power symbol (with the same drawing on a gnd symbol), but it would require to add a local label at each instance. This option seems more error prone.
I’m sure other users have different approaches.

easiest to use global labels like “GND_a” “GND_b” etc

If you press p to add a power symbol in Eeschema, and then search for “gnd” you get some 9 different ground symbols:
If that is not enough, then copy one of those into a custom library and edit it to your liking.
In the end these power symbols result in a global label attached to the wires connected to it, so you can indeed also use global labels.

It is all a bit awkward. Having local labels for GND just doesn’t look good. Being able to join Labels and symbols would be very useful but it looks like a modification is needed. One way for the inteface to work would be setting the footprint field to label:LGND or andy label you wanted.
Maybe I didn’t explain myself quite well. What you mean is possible although the label attached to the gnd symbol will be global. And it can be set to visible in the schematic.
I don’t know how many different grounds do you have in your designs. In mine 4 at most (plus the earth of the mains supply). For example, gnd_in, gnd_power and gnd_out. And sometimes a different plane for gnd_control connected to gnd_power. Or digital/analog grounds, the name it not important.
It is not very difficult to keep track of which ground in used in which part of the circuit, I think.
It would depend on the scope of the label, I’m suggesting how a KiCAD could be improved.
The problem is there are 45 boards in the design connected by plugs. A scheme for each board in one overall project. https://github.com/flypie/SSEM-Baby/tree/master/KiCAD
I see.
In KiCad a project is intended to have a single pcb. Of course, 45 symbols for gnd and for the other power labels is somehow crazy.
I don’t remember only 1 board being in the spec and if I can I’ll order 1 board with all 45 all clearly demarcated with all the routing within the demarcation.
I only want 1 non global symbol for GND. Just the one.
As far as I know power symbols are currently always treated as global labels. For another solution you either have to choose between local or hierarchical labels.
