Forfait Jour France - Setting up multiple unit of measure

For our customer, currently Standard Working Hours are defined at Legal Entity level as 35 hours.

As per the legislative requirements for France, now customer wants to set up multiple unit of measure (for example some employees, standard working hours = 35 hours/week and others work for 5 days/week and this is dynamic in nature).

Is it possible to set up multiple standard durations for the same legal entity?

Note: Please refer the attached screenshots with current and to-be system set up.

Thanks
