Need to update blob storage file without losing existing data

I'm having trouble finding a more efficient way of updating a blob storage.  I'm trying to insert new data into a blob storage file while keeping the existing data.  


Here is how the flow is currently working,

  1. Get new Data
  2. Get Existing data > Parse
  3. Create new array with new data
  4. Apply to each existing data to append to new array of existing and new data (the bulk of the time) - 26 seconds
  5. Compose and Update blob storage with new data

Is there a more efficient way of updating the blob storage while keeping the existing data?
