Changing workable hours per day

Hello,
I'm new to ProjeQtOr but I am quite liking it so far.
I have a question regarding planning a project. One of my resources can work a different number of hours per day, for example, 8hs on Monday, Wednesday and Fridays but only 5hs on Tuesdays and Thursdays.
Is there any way to include this kind of constraint in the planning? I have only seen the option of changing the amount of hours per day but that applies to everyone and not just one resource. I also saw the option of changing the resource capacity but that can only be applied to a fixed amount of days, not for different days of the week.

Is there any way of doing this?

Thank you very much.
Best regards.
