Is there a way to load multiple netCDF files when you use the NetCDF Reader ?

The time axis can be considered as a common time axis ?  
Files store CO2 concentrations every 3 hours during 1 month.

Here are the netCDF headers for first 2 months. I have 20 files to connect and animate.

- first file:

```netcdf
dimensions:
        longitude = 145 ;
        latitude = 143 ;
        time = 248 ;
variables:
        double longitude(longitude) ;
                longitude:units = "degrees_east" ;
                longitude:standard_name = "longitude" ;
        double latitude(latitude) ;
                latitude:units = "degrees_north" ;
                latitude:standard_name = "latitude" ;
        double time(time) ;
                time:units = "hours since 2021-10-01 00:00:00" ;
        float XCO2(time, latitude, longitude) ;
                XCO2:long_name = "CO2 total column dry mole fraction" ;
                XCO2:units = "mol mol-1" ;

```

- Second file

```auto
dimensions:
        longitude = 145 ;
        latitude = 143 ;
        time = 240 ;
variables:
        double longitude(longitude) ;
                longitude:units = "degrees_east" ;
                longitude:standard_name = "longitude" ;
        double latitude(latitude) ;
                latitude:units = "degrees_north" ;
                latitude:standard_name = "latitude" ;
        double time(time) ;
                time:units = "hours since 2021-11-01 00:00:00" ;
        float XCO2(time, latitude, longitude) ;
                XCO2:long_name = "CO2 total column dry mole fraction" ;
                XCO2:units = "mol mol-1" ;
