Combining two epw file

For a city, I have four weather files for different time periods, with some overlap for certain years. The number of data points for a given year is not the same in each file. For example, one file has about 1400 data points for the year 2007, while another file has 720 data points. each file covers ten-year period. Is it possible in Ladybug to combine these files and create a new weather file with a longer time period and more data points?
