Plan overload in "planned interventions" screen

Hello,
In the "planned interventions" screen, is it possible to plan people using over-capacity? For example, a person can have a planned workload greater than 8h per day or greater than 24h per day.
It seems that I can't enter more than two half-days (i.e. 2 times 4h).
Is there any way to plan beyond a person's daily capacity in this screen?
Thanks a lot for your help,
Regards
 

Good day everyone,
Great topic !
Defining over capacity only allows to plan it with the automatic planning as far as I could figure out.
Is it possible to have the over capacity also usable for the manually planned activities ?
Do you, projeqtor product developpers, have in the pipeline to develop a planned interventions screen similar to the timesheets ? Meaning where it could be possible to plan time with more details (per hour or two) ?
Thank you
