Adding the NEW filament CR-M4

I have two different software;

An old version of slicer 4.8.2

A new version of print 7.1

I want in Creality Print 7.1 to ADD a fillament which is not present…how to do it……? to add some new filament…

You can click on the filament that is selected, then go to the bottom of the drop down list: “Add/Remove Filament”.
You can also modify it further by clicking on the pen icon on the right when a filament is selected.
