You would need to add an index column in power query that allows you to look at the value from the previous row.
date_to = VAR currentindex = 'Table'[Index] VAR lastrowdate = CALCULATE ( MAX ( 'Table'[date_from] ), ALLEXCEPT ( 'Table', 'Table'[user_number] ), FILTER ( 'Table', 'Table'[Index] = currentindex + 1 ) ) RETURN IF ( [date_from] = CALCULATE ( MAX ( [date_from] ), ALLEXCEPT ( 'Table', 'Table'[user_number] ) ), TODAY (), lastrowdate - 1 )

Imke Feldmann has created a very useful function for shifting columns up and down:
The article above explains well how you can achieve your goal, but I will give a short summary. First, sort your table. Shift your date column with the mentioned function, the resulting column might be called date_from.Next. Then you can create a new column (like date_to = if date_from.Next = null then DateTime.LocalNow() else Date.AddDays(date_from.Next, -1)) that contains the data you want.
