Can resource allocation in a gantt chart be scaled on a weekly or monthly base?

Question

I use a simple gantt chart with resources. Here a easy example from the website:

@startgantt
project starts 2025-10-01
printscale daily
[Task1] on {Alice} requires 30 days
[Task2] on {Bob:50%} requires 2 days
then [Task3] on {Alice:25%} requires 1 days
@endgantt

when I switch the printscale to weekly the resource calculation gives me the sum of the resources.

I know it's correct, but not intuitive to me. I would prefer a mean value for the week.

Is there a way to make this work?

Thanks!
