Workload week set for a Part Time worker (4 days per week instead of 5 days)

Hello everyone ! 

Does someone know if it's possible to adjust the "week in Wrike" for a part time worker ? I work 4 day / week instead of 5 days for this society that use Wrike. (And the consequence is that If I put hours of "effort" by project, it directly organize it by day of the 5 days week, instead of a 4 days week. The result is that I have the impression that I have a full week to work, which is not the reality because I have one day missing). 

I need to say that I already put my "fridays off for this company" in my Personal agenda in the settings, but this doesn't' appear in my Workload week ! 

Thank you !!! 🙏
