Merge cells with same value without grouping?

[ShelestSergey]

Is there any way to merge cells with same value in column? I have rows such: value1 | 12 | 19.10.2022 value1 | 1 | 12.01.2022 value2 | 7 | 25.08.2022 value2 | 3 | 11.08.2022

I need to merge cells in first Column. Is it possible? Everything I fing is use group tag. But it's more than I need. :)
