[APP][Pro] Power by the Hour [Feature Requests]

Thanks for developing this great app Robin:

I have a couple requests I will separate them in different posts.
First of all:

I mostly use te action: Average price next xx hours is the lowest of the day

for example to start my dishwasher. But the program takes like 2 hours and 20 minutes. So the cheapest block could be different if you calculate the price by minute, since the 3rd hour is only used for 1/3.

Is it possible to implement the action so I can find the lowest average price for xx minutes:
Average price next xx minutes is the lowest of the day

Thank you in advance.
