Is there a way to filter information from a view and display them in the same view?

Question

two months ago i asked this Question: How do i write more complex code in Lotus Notes views. My View now looks like this:

Year	Month	Device	Counter	Times(Minutes)	Times(Hours)
2021
	January
		Test 01		270	4,5
		Test 02		210	3,5
		Test 01		60	1
		Test 01		90	1,5
	February
		Test 01		30	0,5
		Test 02		180	3
		Test 01		60	1

The Database sets a new Document every time a Device is lend out. What i want to do now is to read trough every document and combine "Times(Minutes)" and "Times(Hours)" inside an variable, and also save each device name one time.When a device name is scanned more then once, the counter will go up by one. In my Lotus script program i did this using a Multi-Dimensional Array.

I Want to do this because i want to display each Device only One Time. Then each device has the combined values inside the "Times" Columns, and a counter to show how often the Device has been lend out in the chosen month. It should look like this:

Year	Month	Device	Counter	Times(Minutes)	Times(Hours)
2021
	January
		Test 01	3	420	7
		Test 02	1	210	3,5
	Feburary
		Test 01	2	90	1,5
		Test 02	1	180	3
