Initializing local variables for machine gcode

[Galloant]

Hello all,

I'm currently facing a bit of a problem with getting KAMP to work properly on my Elegoo OS Giga. The printer has four beds which act like a single bed for large prints. Some prints are small tho and only one or two beds need to be heated. Elegoo has implemented following macro in the machine start gcode:

 ;Case 1
	{if (min(print_bed_max[0], first_layer_print_min[0] + 32) - 32) < 405 && (max(0, first_layer_print_min[1])) < 402.5}
		M190 T0 S[bed_temperature_initial_layer_single]
		{if ((min(print_bed_max[0], max(first_layer_print_min[0] + 32, first_layer_print_max[0])))) > 405}
			M190 T1 S[bed_temperature_initial_layer_single]
		{endif}
		{if ((first_layer_print_max[1])) > 402.5}
			M190 T3 S[bed_temperature_initial_layer_single]
		{endif}
		{if ((min(print_bed_max[0], max(first_layer_print_min[0] + 32, first_layer_print_max[0])))) > 405 && ((first_layer_print_max[1])) > 402.5}
			M190 T2 S[bed_temperature_initial_layer_single]
		{endif}
	{endif}

;Case 2
	{if (min(print_bed_max[0], first_layer_print_min[0] + 32) - 32) < 405 && (max(0, first_layer_print_min[1])) > 402.5}
		M190 T3 S[bed_temperature_initial_layer_single]
		{if ((min(print_bed_max[0], max(first_layer_print_min[0] + 32, first_layer_print_max[0])))) > 405}
			M190 T2 S[bed_temperature_initial_layer_single]
		{endif}
	{endif}

;Case 3
	{if (min(print_bed_max[0], first_layer_print_min[0] + 32) - 32) > 405 && (max(0, first_layer_print_min[1])) < 402.5}
		M190 T1 S[bed_temperature_initial_layer_single]
		{if ((first_layer_print_max[1])) > 402.5}
			M190 T2 S[bed_temperature_initial_layer_single]
		{endif}
	{endif}

;Case 4
	{if (min(print_bed_max[0], first_layer_print_min[0] + 32) - 32) > 405 && (max(0, first_layer_print_min[1])) > 402.5}
		M190 T2 S[bed_temperature_initial_layer_single]
	{endif} 

I'm trying got replace the lines M190 T... with a variable, which I can then pass on to the PRINT_START macro. Unfortunately, there doesn't seem to be a way to add custom variables (like in my case bed1, bed2and so on), and I have to work around it.

There is the chance that you can declare or initialize custom variables and I'm not aware of it (even after 5 days of googling), but if there isn't, it would be a nice addition.
