Merge The 2 Indicators into 1

Attached are 2 custom Indicators
1) Supertrend
2) DEMA

I need  
1) Have the DEMA indicator be calculated and plotted  and displayed as a separate buffer on the Supertrend Indicator

2) Change  SourcePrice  from ENUM_APPLIED_PRICE to a  a new enum Variable That can also include the DEMA value

Once you have it done please send me a screenshot of  the Indicator running on chart with the  Type  AP_PRICE_DEMA

enum AppliedPrices
  {
   AP_PRICE_CLOSE  ,     // Close price
   AP_PRICE_OPEN  ,       // Open price
   AP_PRICE_HIGH   ,     // High price
   AP_PRICE_LOW ,        // Low price
   AP_PRICE_MEDIAN ,  //  Median 
   AP_PRICE_TYPICAL ,  // Typical
   AP_PRICE_WEIGHTED , // Weighted
   AP_PRICE_DEMA //DEMA   // THE NEW ONE
  };


input AppliedPrices SourcePrice = AP_PRICE_MEDIAN; // Price source for calculations
