inoput of recharge time series shapefiles

I need to introduce recharge series into FEFLOW but my recharge is, naturally, changing along the area of the model, and changes also across the time series. Meaning, for each time interval (1 month) I have a different map of recharge values. January map values are different from February map and so forth. I need to input these time-series maps into FEFLOW but in spite of reading the manuals I have no clue whatsoever how this is done. Can anyone tell me how do I input such map data series?
