Edit variables through Serial?

Hello in a previous question i was able to set variables through if statements

  const uint16_t inputLength = 512;
int ss = 0;
int bHold = 0;

void setup() { 
  Serial.begin(9600);
 }

 void loop() {
  if ( Serial.available() > 0 )
  {
    static char input[inputLength];
    static uint16_t i;
    char c = Serial.read();

    if ( c != '\r' && c != '\n' && i < inputLength - 1)
      input[i++] = c;

    else
    {
      input[i] = '\0';
      i = 0;

      uint16_t array[80];
      uint16_t j = 0;

      if ( !strncmp(input, "ss", 2) )
      {        
        char* p = input + 2;
        while ( (p = strchr(p, ' ')) != NULL )
          array[j++] = strtol(p, &p, 10); //

        for ( uint8_t i = 0; i < j; i++ )
        {
          ss = array[i];
          Serial.println(ss);
        }
      }

      if ( !strncmp(input, "bHold", 5) )
      {        
        char* p = input + 5;
        while ( (p = strchr(p, ' ')) != NULL )
          array[j++] = strtol(p, &p, 10);  

        for ( uint8_t i = 0; i < j; i++ )
        {
         bHold = array[i];                   
         Serial.println(bHold);
        }
      }

      if ( !strncmp(input, "Whos There", 10) )
      {
        Serial.print("me");
      }
      if ( !strncmp(input, "hello", 5) )
      {
        Serial.print("hi");
      }
      if ( !strncmp(input, "sa", 2) )
      {
        Serial.print("  ss= ");
        Serial.print(ss);

        Serial.print("  bHold= ");
        Serial.print(bHold);

        Serial.println(" ");
        Serial.println("==============================");
      }
    }
  }
}

if works! but if i keep adding variables i have to keep adding if statements and this will get longer. so then i went with code like this that allows me to set all variables at once

#define INPUT_SIZE 30

void setup()
{
  Serial.begin(9600);
  
}
void loop()
{

  while (Serial.available() > 0) {
   

    int _mode = Serial.parseInt();
    int _ss = Serial.parseInt();
    int _bHold = Serial.parseInt();

    if (Serial.read() == '\n') {
      ss = _ss;
      bHold = _bHold;
      mode = _mode;

    }
  }

}

this works awesome! but i have to set all variables at once. my question is is there a way i can simply input a command like ss = 10 press enter then bHold = 30 and not have to input any other variable? thanks i advance. please point me in right direction Maybe make a function?
