Process multiple CSV files to import to MT4 History Data

Hi,

I have multiple .csv files for 3 different time frames. 

I’m trying to import .csv historical data. When clicking on “import” button, it only lets me select one .csv file at a time. Is there an optimal way to do this in bulk via a script so that I do not have to import each separately? 

I would appreciate help from any developers available to help me with this job. 

The time and budget will be negotiable, I am just looking to see if this can be done. As we discuss requirements (if possible) more in depth we can discuss budget and time. 

Thank you
