Summing and aggregating large datasets in PowerApps - Delegation Issues / 100 Gallery Items Issues

Hey guys, 
i have some issues with the common aggregate functions and delegation. I have build an working time recording system with PowerApps in our company. All my Datasources are SharePoint Lists.

One feature is, that the user can select a Month and gets all the days of the selected month with some metadata in a gallery (See Attachment_1).

To avoid delegation Issues i used the following function in the Items Property of the Gallery:
This one works very fine for me in the gallery but my problem comes with the second feature:

I want to provide an hour counter, which counts all the working hours in the selected month for the current user and the current year. (See Attachment_2)

So my first solution to sum the working hours of the current user, year an month was:
Problem: Delegation warning, because Sum() is not delegable


My second solution was:

Problem: Works just for the first 100 Rows in my Gallery. So, if a user has more than 100 Rows in a single Month this is quite confusing for the user, because he has to scroll down the whole gallery, until he gets the correct sum of his working hours...




Has anyone had similar problems and a solution for this problem?
